Black patches on the brain. How on the mr-tomogram, pathologies in the brain are shown. You can decipher the MRI results yourself

Tomographic scanning of the brain is prescribed in situations, if alternative methods can be used to give evidence of the presence of a pathological process in the patient's brain, cephalic vessels, craniocerebral nerves. Behind the images, taken away from different MRI modes, there are such damages associated with new creations:

Kista or brain aneurysm;
Puhlini that brain metastases;
The cyst is upper slit or maxillary sinuses.

MR-research allows to reveal traumatic changes, hematomas and bloody, autoimmune and systemic illnesses on a trivial sign.

Illness of the brain is shown by MRI in chronic headaches

One of the widest symptoms, which indicates the presence of pathology in GM, is the headache of an unintended march. Tse mozhe buti migraine, which is caused through angiospasm, inflammation or organic damage to the brain

Vessel fossa on MRI

On the basis of a trivial pain syndrome, it can be diagnosed average changes speech of the brain of a dystrophic character, caused by vascular disorders. Disorder of the cerebral circulation, spasms and ischemia of the vessels call for blockage, striation of the arterial pressure, decreased memory. At the follow-up on the tomography, a detailed picture of single mid-sized changes in the speech of the brain is shown, which can lead to bleeding (stroke).

MRI may show signs modern hydrocephalus- obtrusive head pain, which is accompanied by boredom, burning weakness and impaired oral function. Illness of this disease - without characteristic symptoms in case of peacetime or minor hydrocephalus. Tomography can recognize the problem at the initial stage, which will help to improve the overall treatment.

In case of untimely diagnostics and the presence of aggravating factors (poor age of the patient, alcoholism, vascular pathologies) develops zmіshana zamіsna hydrocephalus. This diagnosis can lead to total disability and death.

MRI scan of the building expansion of the subarachnoid space- a factor that provokes hydrocephalus (dropsy) of the brain. Particularly relevant is the same for the nemovlyat, oskolki such a pathology is typical for nemovlyat. At the time of the early recognition of the uneven distribution of the root, the doctor can recognize adequately likuvannya, so turn off the development of convenience.

MRI for atherosclerosis of the brain

Ringing of the arteries is the cause of blockage and necrosis of the vessels and the development of a stroke. Causes of atherosclerosis can be as a slump, and chronic ailments (diabetes, obesity, hypertension). MR-scanning of the vessels of the brain allows the identification of arterial lesions, sclerotic lesions.

In the norm on MRI of the brain, the brain on the image may have a gray color. As in the MRI images, the brain is seen with white patches, which is a clear sign of a clear new creation. In order to differentiate the puffiness from a few lumps of tissue, it is important to conduct a tomography with contrast speech.

Dobryakіsna puhlin on the MRI images, the brain looks like a blackout. At a detailed look, it is clear that such fossae form clear contours, on the images there are daily metastases.

When tomography of the head, an assessment of soft tissues is carried out, which allows to reveal cancer destroy chi other bodies.

Hypophyseal adenoma on MRI

For the obvious clinical signs of the chubby process, further investigation of the hypophysis is carried out according to the obviousness of the new creation. MRI is relevant in depressions, if the patient has symptoms, if there are swelling of the pituitary gland or other diseases of the GM.

Tomogram of the hypophysis allows to reveal syndrome empty Turkish saddle- A specific anomaly in the development of the burrow.

What threatens motherland in the brain

In a row with chubby processes, concurrent illness is often diagnosed - swelling of the cystic (head) brain. On MRI swollen brain fixed as an obscure contour of the reduced thickness.

Supchennya rіdini can be caused by both traumatic causes, and pathologies of the vessels and body of the brain. Under the influx, there is a deformation of the brain structures, which can lead to neurological damage (irritability, fatigue, AT drop to critical values, high intracranial pressure). It is very important to carry out MR-tomography in dynamics, stating the results of examination.

Shards of swelling of the brain as a companion of the main illness - swelling, infection and intoxication - then it is necessary to live in until the elimination of the headache.

Cerebral cyst

The presence of empties in the brain, filled with a cerebrospinal mother, is diagnosed by MRI tomography, like brain cyst. Tse dosit wider in all age groups. Causes of cysts can be clogged with trauma, encephalopathy, meningitis, impaired blood circulation in the brain.

Localization sites of cysts can be different in the brain - tunics, shlunochki, vascular plexus. Follow-up MRI reveals tissue accumulation in inaccessible areas. Only this method allows you to see the image pineal cyst, What are the most common illnesses

Lipoma in judgment gossip It is formed from germinal fatty cells of embryonic tissue and is easily diagnosed on tomographic examination. MRI gives the opportunity to show good light and to monitor progress.

As an MRI study showed a cyst on the brain, followed by a negligent implantation of the call to її likuvannya.

Demyelinating process of the brain on MRI

The destruction of the myelin ball of the white speech of the brain is an irreversible process and accompanying autoimmune disease - zocrema, rozsiya sclerosis. This illness often does not have clear symptoms at the cob stages, which is especially important for conducting tomographic diagnostics.

Drives for MR-scanning can be healthy damage, neurological disorders. When deciphering the signs, they can be guarded pits of demієlinіnіzatsії, Yakimi can accurately diagnose illness.

Magnetic tomography allows to identify the middle of the damage to the nervous system in diagnosing autoimmune diseases. It is rather difficult to make a clear diagnosis of “rozsіyany sclerosis” after the results of MRI.

Chi is seen signs of pink sclerosis on an MRI? So, when scanning GM, plaques, characteristic of this disease, are clearly seen in white speech. The sockets of pink sclerosis can affect the brain stem, the brain. By the fact that it looks like a hole of pink sclerosis in the photo, the type of illness and the variant of overcoming the illness are recognized.

Krіm razorok GM, widening spinal rіznovid ailments. With this type of pink sclerosis, MRI of the spinal cord indicates the collapse of the myelin ball on the nerve fibers. In case of pathological zones, they can look like small pits (on the cob of illness) or affect the entire spinal cord. MRI accurately shows the localization of rosaceous sclerosis, which allows compensating for disease at an early stage.

Crime of pink sclerosis, MRI shows such a non-sickness, like morbid amyotrophic sclerosis(Injury to the rukhovyh nerve fibers, which leads to muscle atrophy). The development of the syndrome at the cob stages allows the development of the disease to improve.

Stroke or brain infarction is a pathology of the GM, provoked by impaired blood circulation. As a result of spasm of the vessels or thrombosis, the middle tissue necrosis of the brain is established, which can lead to serious consequences. Anterior stroke may be arterial hypertension, encephalopathy, atherosclerosis of the vessels of the GM.

stroke can be used in such forms:

hemorrhagic;
ischemic (width up to 80% in the total number of fluctuations);
subarachnoid.

On MRI, all stages of ischemic stroke are indicated - from acute (up to 24 years) to organizational (1.5-2 months). Even at an early stage (10-14 years old with an onset of stroke), the signs clearly show damage to the parenchyma of the GM, thrombosis and embolism in the vessels of the GM.

At hemorrhagic stroke CT or MRI allows you to reveal the middle blood. With this magnetic tomography, it is possible to recognize a hematoma after a few days after the cob of ailment, while CT is effective for the cob of stroke - in the first year.

For maximum accuracy of the brain MRI scans, sedation is performed, which allows patients with a stroke to rest at a quiet place for an hour of the procedure.

Anomalies of the brain on MRI

High efficiency is shown by MRI scanning in the development of the brain, especially in the child's head. For additional tomography, the following are indicated:

anomalies of white / gray speech;
venous sinus defects;
pathology of the vessel bed and the healthy artery of the GM.

The scientific articles are full of importance MRI in schizophrenia caused by anomalies. The signs clearly show the supra-mundane development of the mucosa of the brain and the change in the structure of the white speech of the GM.

Magnetic tomography at times wins out as an early diagnosis of illness, so monitoring will become a patient for an hour of rejoicing.

What shows the inflammation of the brain on an MRI

Diagnosis of inflammation of the brain (meningitis, arachnoiditis, encephalitis) is an important task. Calling for the joy of the ignition process can lead to important complications, even to a lethal result.

Inflammation of GM can be caused by infectious microorganisms, most often on aphids of low immunity. Yes, at toxoplasmosis brain MRI showing the numerical ruining, honed with embroidered fabric. The presence of a post-infection middle of the infection calls for the ignition of the GM process.

At meningitis findings in the MRI of the brain are seen in hydrocephalus, viz. The tomographic study of the contrast enhances the informativeness of the scan and allows to reveal direct signs of illness - strengthening of the meninges and furrows.

Recognition of ailments and daily therapy can lead to complication:

cerebrate;
brain abscess;
neurosarcoidosis/sarcoidosis of the brain.

The rotted middle parts of the GM stricken area in the images, taken away by MRI, may look bright and easily see the new creation.

Encephalitis of the brain characterized by a viral nature. On MRI-images, broken by the passage of the first days of illness, singly or symmetrical centers of infection appear, which penetrate the white speech and the cerebral cortex.

Until fuse zahvoryuvan GM can be seen vasculitis of the brain What is characterized by damage to the vessels of the brain? Differentiation of vasculitis is possible due to the presence of MRI, on the basis of the laying, an appropriate therapy is prescribed.

MRI for neurological pathologies of the brain

The effectiveness of MRI in diagnosing pathologies of the craniocerebral nerves and the state of the central nervous system of the brain is a proven fact. For the help of a ball exchange scan, the following discords appear:

Alzheimer's disease, Parkinson's disease - caused by the death of neurons and cognitive/rukhovy damage;
Epilepsy- MRI is carried out using the 3 Tesla program for accurate diagnosis and the inclusion of GM puffs, recognition hippocampal sclerosis - one of the causes of epilepsy;
Glose pits- Replacement of damaged nerve cells with scar tissue.

For the diagnosis of damage to the craniocerebral nerves, the following are prescribed:

MRI at trigeminal neuralgia- for the presence of acute pain syndrome in the area of chewing gums and empty mouth. Dosledzhennya allows to reveal vascular conflict(like from the tripartite, so with the facial nerve).
Tomography at neuritis of the facial nerve- in case of viral infections, m'yaziv disguise.
MR-scanning of the eyes - the procedure is carried out for diagnosis atrophy of the zore nerve and other pathologies of the light analyzer. MRI description at g laucoma eyes clearly pointing to degenerative changes in the zonal nerve, after which the internal pressure moves.

Does the MRI show a pinched nerve?

With tomography of the brain and spinal cord, instilled with contrast, visualization of the strangulated nerve ending is impossible. Prote MRI gives the ability to reveal the causes of zatiskanya - fusing processes, swelling, hives, constitutional anomalies.

MRI reveals illness, as if it were not associated with the brain, but squeals from neurological damage. So, sometimes with cystitis MRI of the brain may be recognized - so there is a possibility of neurogenic sciatica syndrome.

head injury

MRI on impact head injury(TBI) - a method that allows you to reveal the microdisorder of the brain, the building results in a negative way for a long time. Hematomas, which are not recognized at any time, can provoke neurological damage, decreased vision, hearing.

Magnetic tomography at chicken brain does not show changes in the GM, therefore, for diagnostics, the coward is not vikoristovuetsya. Scanning after a call reveals aggravation, caused by a trauma of the skull - headache, post-traumatic encephalopathy, mental recovery.

Visnovok MRI of the brain fixes the norm and pathology in the brain, central nervous system. With a normal tomogram, the standard thickness and miscarriage of the brain tissue, the presence of hematomas, hemorrhages, and any ablutions are indicated. Such an MRI result is a fault of the rules, but the MR examinations are carried out for the presence of sufficient evidence to confirm the diagnosis.

Method of medical diagnostics - magnetic resonance imaging (MRI) foundations on the physical phenomenon of magnetic resonance of protons in water in a magnetic field in the presence of an influx of radio waves. The high efficiency and absolute non-shockiness of this method made it the most efficient and informative for today's day in medical visualization. This allows you to select MRI for different age categories of patients - children, young adults, adults and adults. For the help of MRI, it is possible to assess the follow-up of various organs and systems, as well as indirectly or directly evaluate their functions.

Types of magnetic resonance imaging

Low-altitude tomography 0.2-0.5 Tesla,
High-capacity tomography 1.0-3.0 Tesla,
Supratemporal tomography 3.0-9.0 Tesla and more.

Low-altitude tomography may reveal a contour - tobto. are 2 large plates of a permanent magnet, one-on-one (top and bottom view of the patient or right-handed and evil view of the patient). In fact, from the sides of the mouth, from the front, and from the back, the patient is resting at the open space. It is not suitable for patients with claustrophobia and less likely to be afraid of closed space (people cannot ride in elevators and the subway), these tomography data are not suitable for these patients.

On this butt of the view of the transverse-creeed ridge of the ridge, it is shown the sharpness of the marks, crushed on various devices with a different magnetic field strength (from low to high - from 0.3 Tesla to 1.5 Tesla). Obviously, the greater the strength of the magnetic field - the better the brightness of the picture. Ale, do not fall into the oman of linear fallowhood "the stronger - the better".

Not torture not tіlki vіd yakostі Magnіti, but ya vіd yakostі catushok, yakі sleep on the Pazіntta, Vіd Sorih, Shaho Ovroblya, Sorih Done, Nalashtuvannya Wedgenda, the behavish of the pazіntta pіd hour Dzorzdzhennya (Vivily Zherіgati Nerchukhtu Tu Disciplinary Vikonuvati qualification of the MRI operator, which is to carry out follow-up.

High-capacity tomography may close the contour - tobto. can otherwise be called "closed", - long-term tube with open cuts (through which the patient is on the table in the middle and, in fact, is in a "closed" space (front, back, left-handed and right-handed, the walls creak, and the tomograph tube does not curl up to the top and bottom) - do not cover closed spaces) Given the position of the patient with a stretch of 15-45 hvilin, it can be twisted in ailments with claustrophobia.

Scanning areas and views

In MRI, like in anatomy, the human body is traditionally divided into three planes and three awns. The image below shows the main area and the views that show them.

MRI allows you to treat changes in the internal organs of a person in case of various illnesses without contacting the body and without disturbing your work, which other conditions in medicine cannot do today. As a result, the image is taken away from different planes, including the late (sagittal), transverse (axial) and frontal (coronal) ones.

On this image (below), we are trying to convey to you the principle of spreading the views one to one.

Scanning starts from the beginning of the patient’s growth at the tomography and then the tomograph conducts low sightings of low density. This is the name of the target sign of the localizer. Too many fahіvtsіv (doctors not MRI) pardon them like everything else and think that MRI is nasty, I want to bring the foldability of the robotic doctor and the MRI operator for the first time and make that superficially unimportant setting up to the robotic radiologists.

After the sighting (rozmіchalnogo or reconnaissance) scanning is carried out, the viewing of the planes of views, with additional anatomical landmarks along the traditional axes, is carried out. Stars are displayed at the singing number with specially given parameters. The number of spores that are not directly at all however, and fall due to the pathological changes that appear in the body, change for an hour directly without intermediary during the course of this study. Do not allow to re-standardize the legacy of one and all. At any rate, the number of patients and supplementary programs should be conducted until the hour of scanning is increased, so that it can be adequately acknowledged by the patient, the doctor and the other patients, if they check on their card.

After the scan has been carried out, sights appear at three flats.

The work station of the MRI operator is to complete the folding instrument with the mass of parameters to achieve the optimal imaging result. For such a great number of parameters, the hour TE, the hour of relaxation of the cores of the water TR, the matrix, the comradeship of the mind, the direct view, the level of vitality, the field of view FOV, the number of views and a lot of others. Most of the doctors, who have never worked on an MRI, do not show their own complexity of follow-up, and may be all patients care that the follow-up is carried out by pressing one button. And the doctor’s recommendations about “a comradeship of 1 mm” are simply anecdotal, if you just take the task of following up to respect, what you face in front of the tribute, plan a lot of tribute, less than one of them to become a comrade’s vision and optimally not visualize. If you don’t get hung up on the status of the article, please, if the MRI doctor and the MRI operator are professionals, know your work better, lower the surface of the appearance of a lot of doctors, tight with the higher steps and other regalia from the side of diagnostic advice).

Impulse sequence

MRI shows different imaging modes, including the most common ones: T1, T2, Flair, Stir. Qi regimes allow to infuse tissues and motherhood to the body, which has the power of various physical authorities to fallow in them water: blood, fat, soft tissues and thinly.

Mode T1 has dark ground and light fat, T2 mode has light fat and light ground, Stir mode has light water and dark fat. Flair - wicker for the development of the speech of the brain.

Main features of MRI and CT

Magnetic Resonance Imaging (Nuclear Magnetic Resonance Imaging), briefly - MRI.
Computed tomography (earlier often used the term X-ray computer tomography - CT), briefly - CT.

MRI and CT are fundamentally different physical bases for taking these images. MRI of the vicorist magnetic field and radio waves (not short-term for humans), and CT of vicorist X-ray changes (during the process of conducting CT scans, it is necessary for the organism, however, in a small dose and with frequent victoria, it can be harmful for humans).

MRI benefits:

good tissue contrast of soft tissues (you can clearly see the structure of soft tissues, or the structures that avenge the motherland: the internal organs of the empty stomach, small pelvis, brain, mucus, ligaments, meniscus),
non-shkidlivist for the body (you can work like a regular for a long time and often),
allows blood circulation in the vessels (arteries and veins) of the brain without contrast (!),
allows to carry out functional investigations: functional MRI, spectroscopy, perfusion without contrast.

CT benefits:

good tissue contrast of the underlying tissues (brightly visible cystic structures, pathological changes in the brushes and legenev tissue),
svidkіst dolіdzhennya (majzhe be-yakе dolіdzhennya on CT ide no more than 1 hvilin),
practically, it is necessary to contra-indicate until the next time (the last time you can go through any kind of ailment),
there is no closed space (steel passes through the vuzka frame of the tomograph, it does not blow the tunnel).
CT perfusion may be more variable and quicker, lower on MRI.

It is best to demonstrate the view of MRI in CT on the butt of showing a transverse-creeed ridge on MRI (upper row - in T2, T1 and STIR modes) and lower row of CT in soft-tissue mode, brush-line and in SSD format).

The method of 3D-reconstruction of thin views on MRI makes it possible to visualize three-dimensional images of arteries and veins, as well as other anatomical areas, and on CT scans of the skeletal reconstruction, it is even more likely to be performed during planned neurosurgical and orthopedic operations.

A demonstrative example of the recognition of 2 methods (CT and MRI), carried out to the same patient with great puffer in krizhah. MRI clearly shows the structure of the plump conglomerate (you can evaluate the structure of the plumpness, homogeneity, the presence of cysts or necrosis, as well as the appearance of a border). On CT can be used by Otsіniti Zherestenna Kіstkovo-ї Resting the Kіstka structure in your Pukhlinnaya M'yky-said conglomerate (Chi Obrostє Pukhlin Kіstka Abo Violating in Kіstku, Chi Ruinє Kіstka Abo Calling to ї Patologica Divine, and so the Owiniti Furnivnya Ruynuvannya kіstkovoїї).

In this case, the patient has a compression fracture of the body of the ridge. MRI visualizes the contour of the cyst and may reveal a swelling of the cystic brain in the spine (to increase the number of visnovi about a fresh or old fracture). CT demonstrates well the structure of the cystic tissue of the ridge itself, the presence of the cystic ulamki, their number, expansion, zsuv, especially the importance of the posterior support complex of the ridge (loamy ridge, arch, lower ridge), which is extremely important for planning the operation of this patient (preservation of the ), as well as the planning of operational excellence, or even the most recent time of the operation (navigation).

Matrix and tovshchina in sight

A view (scan) on an MRI is not just a flat image on a screen. There are some specific features that characterize the quality of the picture on a new one.

There are two main parameters: a matrix (number of pixels - small dots or squares near the plane, skin for height and width in the coordinate grid along the x-axis and y-axis) vimir - height = Z at the spacious coordinate cell).

On the picture, which is being accompanied, the appearance of a simple pixel (points - a fine element of the image in the coordinate space) is demonstrated, as well as a parallelepiped - a voxel (a cube - a small element of the image in the space of the coordinate space) from the image view.

The matrix can be twisted (one of the sides is wider or narrower) or square (side A = side B or the width along the X axis is longer than the width along the Y axis). This is how the square matrix is twisted, and the width of the matrix outweighs the value of the matrix - you can talk about anisotropic voxel(that's a paralepiped). As a square matrix is victorious, and the width is equal to the value of the matrix - next talk about isotropic voxel(tobto cube). Tse nadalі Mauger vplinuti on zovnіshnіy viglyad reformatіv, tobto vikoristannya zrіzіv for pobudovi zrіzіv in іnshih ploschinah, vikoristovuyuchi tіlki zrіzi in odnіy ploschinі for vіzualіzatsії danoї anatomіchnoї oblastі in іnshih angles (y ploschinah іnshih zrіzіv - napriklad, if Je tіlki poperechnі zrіzi and E for with the help of computer processing, it is possible to induce them later).

In medical stakes and among patients, there is a broader idea about those who are thinner in terms of the quality of diagnostics. Another part of the argument for the self-righteousness of this thought is to serve as a statement about those that some other resolution can be missed, if it is squandered into the gap between the gaps, or to the edge of the other gap, after which it appears to be missing, and as a result, cancerous fluff may spread out from the new one.

In fact, the point of view is more superficial, even though logic is not spared, it is still not fair.

In most of the cases, regular robots on MRI show signs of 3 to 5 mm. In the most important cases, such a community appears to be sufficient for successful diagnosis of various pathological processes. In this way, it is necessary to recognize the presence of such a decision thinner than 5 mm, so it is not practical to use it in the gap, so it’s possible to pass through in 3 planes and in this case, the other hearth is to blame, but even more so, in order to avoid hitting all three planes of scanning, on the skin of the flats. In such a rank, such a cavity can be 3 times thinner than 5 mm so that, for the theory of imovirnosti, it would not be possible to spend one time in the scanning area. Ale, the whole problem of yoga diagnostics is not in the fact that you can’t eat wine at a glance, but in a different way. In this case, the next step is to say that the most modern look (morphology) on MRI allows you to see one light to one group of pathological processes, and even to another. The starry look illuminated with rosemaries of 5 mm and less may look at one point on the picture. At the Czeom Sensі at once, there is no clear point in the body of the ZOVSIM, I don't mean a cancer in Pukhlini in the pokhykovіyi stadium, and Bіlshoi Miroi є Roshkodau, Pälshoiy, I am a sobrenha (artifact) of Aboy (Sudina, Nerve), an anatomy budovi chi chimos, scho to go between the diagnostic efficiency of the method. Practically, in any case, you can find a cavity larger than 5 mm, so it’s important to be more specific and mother 100% primed for your point of view. I thin zrіz not virishuє tsikh zavdan.

With all that being said, a subtle view adds problems to the picture, as can be seen in the representations of the views. A subtle view of the slid in victorious cases, as in the case of a doctor, a radiologist, from the development of specially adjusted programs, as well as the development for specific anatomical areas and the development of specific medical diagnostic tasks. For example, a thin streak for the treatment of a few nerves on cisternography (impulse sequence of a practically binary black-and-white color, which allows more than a contour organi on the interphases of the rіdina / soft fabric) or a thin streak for planning stereotaxic radiology ().

Contraindication before MRI

MRI is a non-standard and widely used diagnostic method, it can be calcified, and it can be divided into absolute (additional is not allowed!) and final (additional negligible, but it can be clinically invariable and important for the life of the patient).

Absolute contraindication

insertion of a pacemaker (changes in the magnetic field can change the robot and disrupt the heart rhythm, which creates a threat to the heart rhythm and myocardial speed) - MRI IS IMPOSSIBLE for life indications!
ferromagnetic or electronic implants of the middle ear (risk of damage to the inner ear or a breakdown of the device itself),
large metal implants and ulamki (third-party bodies of unknown nature, possibly metal),
magnetic metal bodies, implants: Ilizarov apparatus or endoprostheses (in the area of follow-up, it is possible to carry out visualization up to the day of visualization, as if given by a third-party body not in the area of follow-up, the procedure is permissible in most cases),
clips, stents and kava-filters of the empty stomach (risk of development of internal bleeding),
internal injectors to insulin (it is possible to change microcircuits or batteries),
body weight more than 150 kg (in some cases, 120-130 kg is already unacceptable),
Another reason why the medical staff should worry about it will be more unsafe for sickness or endanger the life of the patient (in such situations, it is necessary to take a consultation or care from relatives / the patient himself / the caretaker for the benefit of the day).

Vіdnosnі contraindications

claustrophobia,
epilepsy,
vaginess (especially the first trimester),
end the heavy camp of the ill,
impossibility for the patient

Artifacts on MRI

Artifacts on MRI - tse changes on the signs, which can destroy or complicate the visualization, and also simulate the presence of changes, which is not clear, but mask the changes that may be true, but because of these, the transition is not visible on the sign.

Artifacts are absolutely different, which lie in the robotic apparatus, the presence of third-party material in the hallway, or the physiological features of the patient, but all the stinks are divided into groups of reasons, or I will show it.

Artifact of overlaying calls to wrong planning reasons - a pardon for the MRI operator, which can be corrected by a larger field of vision and lie down in the presence of the medical staff, as well as in the case of the installation of the device by the head of the owner.

An artifact of the heterogeneity of the magnetic field - calling out the presence of metal objects near the centerless proximity to the view gallery. So in my case, through the braces on the teeth, the vinication of the image was bloody in the furrows of the frontal part. These artefacts do not call forth a miracle from fakhіvtsіv - MRI doctors, but they can also be the beneficiary of a doctor, who can't be informed about the possibility of contemplation, viklikanі zalіz, roztashovanim order from the zone of follow-up.

An artifact in the form of metal is the same artifact as in the heterogeneity of the field, but in the area of investigation of the building's faults, the anatomical region is intact, not facilitating the diagnosis, and the teeth are completely impossible. At the same time, the radiography clearly demonstrates the expansion of the endoprosthesis of the knee joint along with the large milky and stipe cyst.

Artifact in ruins. Under the hour of the MRI scan, it is important to protect the integrity of the entire scanning procedure. Otherwise, the picture shows elements of dynamic inconsistency and brightness, which sometimes complicate the diagnosis, and sometimes it’s not possible to work.

Artifact flow. In the body of a person, not only the blood and the heart are collapsing all the time, but also the spinal cavity in the empty skull and the spinal canal. When MRI of the ridge in the thoracic vіddіlі often zastrіchayutsya "dilyannya signal", zumovlenі flowing ruh of the spinal cord, scho in delіtantіv pomilkovu vzhennia about the presence of the appendages near the spinal canal, such actually none.

Sometimes artefacts to the flow in the normal day and night are due to different turbulence (vortex) flow. For example, if the flow of the spinal cord crosses the cyst in the spinal canal, it is not visible on the most prominent tomograms, but the swirl of the flow at the edges and a small displacement of the spinal cord is obvious for obviousness.

Contrasting strength

If necessary, the doctor can recommend patients with contrast enhancement.

Contrasting strength- tse internal introduction of a special drug that is not safe for health, which accumulates in a larger number in the changed tissues in different proportions and volumes of the fallow in a typical pathological process and th phase of the transition. Tse help the doctor to determine the nature of the illness.

Why do you need to contrast stronger:

differential diagnostics (to clarify the nature of the revealed changes),
clarification between the development (the breadth of the pathological process and the exact definition of yoga between),
to clarify the number of metastases, for example, in the brain or liver,
for planning stereotaxic radiosurgery,
to assess the recurrence or continued growth of swelling after її removal or prominence,
for assessing the phase of activity of the ignition-demyelination process (rosy sclerosis),
MRI of the arteries and veins of the brain does not affect the introduction of contrast (based on physical changes that are formed by the flow of blood in the vessels, MRI will show a picture in Time-Of-Fly or Phase-contrast mode).

In some cases, patients are blamed for doubts about the need for contrast enhancement. What is wildly natural, but not rational. Contrast victorious is not like an additional "service", like a doctor is given to the company to increase the price, but it is an important tool for improving the diagnostic efficiency of the MRI method. In contrast, one can say a lot more about the manifestations of non-domias, or a cumulative pathological process, and sometimes the growth of red wine. In this way, as the doctor recommends an MRI with contrast - not a trace. Prote, not varto independently, without the recommendation of fakhivtsya to influence the conducted MRI with contrast, the shards of a healthy yogo vikoristannya are not true. So do not varto razrakhovuvati, so that the contrast can be revealed EVERYTHING that could be but, or with the contrast of the image, you will become helpless. Contrast does not give the necessary information, but sometimes it can be super chalky and the results obtained with contrast are no longer necessary to give information to the doctor for molding the visnovki, and not to ensure that the absolutely reliable clinical nutrition is absolutely reliable.

On this butt, it is good to see, as if looking good, the plumpness of the nerve cortex in the spinal canal on the last without contrast (native MRI) and after the introduction of contrast (the plumpness intensively and uniformly accumulates contrast, becomes bright).

Contrast drug - hypoallergenic method, oscalki vin - non-ionic hypoosmolar chelate complex of puddle-earth metal gadolinium. Today, there are a lot of commercial names of contrast agents on the market, for example, in MRI there are paramagnets: Magnevist, Primovist.

The method of introducing contrast in MRI sound 2: internally strumine (superior internal injection) and dynamic contrast (there is a quick contrast injection during scanning (by the MRI operator through a catheter or with the aid of a special device - an injector).

Sound vikoristovuetsya the introduction of a contrast agent with a rosemary of 0.1 ml per 10 kg of body weight of the patient. Zzvichay injected vіd 10 to 20 ml of contrast.

The second example of demonstrating better contrast on MRI, it is shown de livoruch how it looks like on MRI spinal canal neuroma with contrast: 1 on a thin view (the image does not look the best - it turns us to nutrition about the pardon of the need for a "thin view"), 2 on a fine MRI in T1 and 3 modes on MRI in T1 mode with visible fat tissue (Fat Saturation mode) - which leads to the best visualization of the structure between the swelling at the spinal canal.

MRI: T1-rank axial look. Chervona arrow (1) indicates the right pіvkulyu of the brain, (2) - sіra speech, (3) - white speech

Brain changes on MRI can be caused by various reasons. Fahіvtsі vpevnіnі: the sooner you get sickness and rozpochat likuvannya - the more chances for a successful result. Magnetic resonance scanning of the vessel's head can be seen by most people without any serious side effects and further traces. Such contrasting speeches based on gadolinium chelation in 98% of cases do not show any improvement. The only serious transition to a diagnostic procedure is the presence of metal in the body of a person, which will require another method of investigation, for example, CT.

Rozpodil white and gray speech and pathological processes in the middle of the brain reportedly illustrated by MRI. Magnetic scanning is one of the high-precision non-invasive methods of instrumental diagnostics in neurosurgeons, neurologists, and, more recently, psychiatrists.

Rozpodіl syroї and white speech near the brain

Sira speech

Sira speech of the brain is considered to be the most important function of the nervous system and is represented by the bodies of neurons, glial cells, clusters of dendrites, the thinnest blood-bearing vessels - capillaries - and unmyelinated axons. The main histological structures are centers, skin with some kind of control, be it to do: the act of secession, defecation, heartbeat and other. Neurosurgeons are in vvazhayut syriy kolіr razumny, svidshe, tsya substance may be earthy sounds. The warehouse of the main structures of the brain is clearly marked, more importantly, through retail, instead of water and proteins. Tse allows differentiation on tomograms one zone in the outside. Pathological processes, localized in the Syrian speech, lead to destruction of spriynyattya, mov, emotions, memory, sensory sensitivity, will, m'azovih ruhіv and іn.

Bela speech

The white color is surrounded by bundles of nerve fibers, covered with a myelin sheath. The main function of the cerebral structure is the transmission of impulses from the main centers to the periphery (lower lankas of the nervous system).

What kind of brain disease is shown by MRI?

Change white speech on MRI for various pathologies

Carry out for diagnostics:

puhlin. MRI is one of the highly informative methods in the detection of oncological processes in the brain, allowing the establishment of a relationship between the neoplasm and the abnormal tissues;
metastatic lesions (swelling). The brain is rich in evil new creations - the meta organ.
cavities that appeared on aphids of various angiopathies, hypertension, atherosclerosis, migraine, hyperhomocysteinemia;
inflammatory processes, including those of an autoimmune nature: pink sclerosis, sarcoidosis and others;
infections: VIL, tuberculosis, herpes, neurosyphilis, mycoplasmosis and in;
post-traumatic changes after a direct blow to the head or for revealing the follicles after a promenade therapy, which is also considered by radioroentgenologists as an altering factor;
various metabolic disorders, toxic damage;
heart attacks and strokes, ischemia, dyscirculatory encephalopathy (impaired blood microcirculation is manifested by hypoxic / dystrophic changes in the brain);
juvenile malformations;
anomalies and vad development.

With some ailments, do the middle parts of the brain appear on an MRI?

The principle of stimulating the image during MRI of the brain of the foundations on the combined multiplicity of views, sizes of 1 mm in a single cell, but the skin ball can be assessed okremo

The butt of the attack of a simple speech with the folds of the pits can be heterotopia and the most common її variant is subpendymal, as it is associated with epilepsy and zatrimkoy development. In the diagnosis of pathology, magnetic resonance scanning of the brain is more important. Epilepsy attacks can be blamed on the head, which requires the inclusion of swelling. Changes in the gray speech are known in schizophrenia (loss of tissue thickness in the upper frontal frequency, left upper lateral line), bipolar disorder and other. The pits in the brain of a sick person who suffers from mental disorders, often know, but the main criteria for diagnosis

Differentiation of the pathology of white speech includes a whole range of illnesses, but also shows the villagers, as a rule, to speak about illness and a variant of the norm in age-old people. Stop entering at the understanding of the "good old brain". Destructive zones can trap and natomist hypoxia, ischemia. On MRI, changes in the white speech of the brain, associated with moderate lesions, are found in:

On the MRI sign of the change in the white speech of the brain: green arrows point to multiple demiliosis of the fossa in case of pink sclerosis

Rose sclerosis. MS - fuse (autoimmune) disease, which is caused before the appearance of patches in the white speech of the brain. The pathogenesis of nevidomy. Similar cases are known for herpesvirus infection, leukoencephalopathy, intoxication, so before making a diagnosis given by tomograms, it is necessary to evaluate after analyzing the clinical situation and testing the liquor. MRI of the spinal cord is often required.

MRI: hostile rozsіyany encephalomyelitis

Gostriy disseminated encephalomyelitis. Multifocal lesions on tomograms appear 1.5-2 days after contact with a worker or vaccination. The process may be affected by other structures of the nervous system. I will improve the visualization of the follicles for safe contrasting. The rozmir demієlіnіzovanіh dіlyanok greater, nіzh with rozsіyanomu sclerosis, illness is often diagnosed in young women.

MRI: Neuroboreliosis (tick-borne encephalitis)

Sick Lyme. Magnetic resonance scanning demonstrates dots in the middle, and the picture can be seen in case of autoimmune diseases. Ale for cієї nosology is also typical specific visip on the skin and unwell, which predicts a cold, arthralgia. On the tomograms of the lower abdomen, there is a hyperintense signal from the side of the spinal cord and the accumulation of paramagnet in the area of the root zone VII of the craniocerebral nerves.

Sarcoidosis on MRI: yellow arrows indicate lesions of the tunics, cranial nerves, similar changes present in stovbur

Sarcoidosis of the brain. Diagnosis can be easily established by magnetic scanning, sometimes residual verification is required after biopsy is taken. The picture on tomograms suggests changes that are characteristic of pink sclerosis.

Negative dynamics on tomograms, monitored at monthly intervals in leukoencephalopathy

Progressive multi-ligamentous leukoencephalopathy. Pathogenetic factor - infection with Cunningham virus, people suffer from immunosuppression (symptoms of a damaged immune system). There may be damage to the arcuate fibers of the white speech, with a contrasting intraday effect of accumulation. Pathological pits are most often localized on one side, sometimes symmetrical changes can be seen.

Dystrophic changes in the brain on MRI

Cerebral angiography

With impaired blood flow, sourness and trophic starvation of clitin (ischemia) develop. Tse lead to degenerative processes and accompany dysfunction. The degree of diversity of the rest is variable, to lie down in the event that I won’t be able to get blood, or the frequent tide will be saved. Dystrophic changes can be local or diffuse. Total damage to the brain is recorded in meningitis, encephalitis, moderate type changes for cysts, minor ischemic processes, forming post-traumatic scars.

Clinical manifestations may include:

head bіl;
high blood pressure;
the appearance of paresthesias (obvious names or generations in clinics); vipadanya sensitiveness;
lowered the dawn (even to the point of blindness, which is to say about the damage to the star's nerve), memory, lowering of intellectual zdіbnosti;
sleeplessness;
hyperkinesia (uncontrolled shortness of mucus) and sudomi.

With progressive pathology, paresis and paralysis, it is important for the first symptoms of unfavorable growth. One by one, the middle ones can appear in young people and women and do not know about the pathology. Tactics of the doctor - dynamically vigilant and conducting repeated magnetic scanning after 3-6 months, so as not to miss the development of any serious illness, for example, pink sclerosis. In women older than 60-65 years, cavities are known practically in all patients, which explains to natural old people. These changes are irrevocable, but the progression of the process can be corrected if adequate litigation is recognized.

To provocative factors include:

chronic alcohol and nicotine intoxication;
stressful situations;
irrational mode of practice and recovery;
obesity;
low rukhov activity;
stіyke promotion of arterial pressure;
circulatory diabetes;
hypercholesterolemia.

The type of dystrophic lesions in the gray and white speech of the brain on MRI depends on the nature of the pathological process.

Judicial brain imaging on MRI

MRI: ischemia zone in stroke (shown as a red oval)

In case of suspicion of cerebrovascular pathology, special attention is paid to the arteries during MRI of the brain. Follow-up may be on the introduction of contrast, and it will sound magnetic resonance angiography. In urgent situations, in case of ship accidents, CT scans are needed, X-ray diagnostics takes less than an hour and clearly demonstrates the zone of relief in case of hemorrhages, and after stabilization of self-imposed magnetic resonance angiography with a primer. The study shows atherosclerotic plaques, thrombi and aneurysms (vipination), their localization, wall deformation.

In case of ischemic stroke, magnetic tomograms show darkened areas of irregular shape, which are visible on a computer scan until the end of the first stroke. The injury is often one-sided. Blood bleeding from the judge, which burst, gave intense light contamination, but only in the first year, the second time from the moment of the catastrophe, and then on the MRI it became invisible, although it was clearly visible on the CT scan. As a result of a stroke, a pseudocyst is formed, filled with a mother tongue, deformation of the nerve tissues is manifested. MRA is indispensable in the diagnosis of tumor angiogenesis. The vascularization of the pathological fossa has been strengthened, and it was suspected that the evil newborn, like growth, live for the raised blood rush. If the judges do not reach the growth of swelling, they show cases of ischemia, necrosis.

The norm of magnetic resonance imaging of the brain

MRI of the brain, normal

The norm of MRI of the speech of the brain - it is clear to understand what to lie in the eye, the patient's status, changes on the tomograms of the obov'yazykovo izstavlyaetsya with symptoms. The doctor assesses the symmetry of the chastices, the size of the shlunochkivs, the vessels, the evenness of their filling with contrasting speech, the presence of new creations, malformations and richly іnshoy. The computer program vibudovuє sharovі izobrazhennya, after slidіdzhennya їх others on plіvki and look, rozmіshchuchi on a negatoscope. They gave the application form to be filled in, declaring an earlier diagnosis. It is hardly possible to independently decipher the MRI of the brain without special training: a person is not known to wind up like a hole, not to figure out what caused it to appear. All food can be supplied to the doctor, who will carry out the follow-up. In unclear situations, due to ambiguous results, another thought was substantiated. Often patients, having read the words "newly created, puhlina, NEO" at the visnovka, are reminded of the prospect of being ill by a radiologist, who knows bad luck. On nutrition, the neurosurgeon can review the results of the biopsy. In order to complete the picture, it is necessary to add additional MRI of the cervical spine.

Deciphering an MRI is exceptionally foldable and on the right, which is what radiologists (radiologists) are professionally engaged in. And often, patients, having passed the cold, themselves bachat deyak zmіni on the signs, and ask what the stench means. This article is written to help such patients. Similarly, the article will tell you about the vindictiveness of another thought.

MRI OF THE BRAIN: BILLI SPOT

One of these foods is that behind the white patches, specks can be seen on the MRI images of the brain. Normally, the structure of the brain is clearly uniform, but in case of various ailments in the brain tissue, you can see the patches, which are disturbed by the color (as it seems to be fahivtsі-diagnosis, the intensity of the signal) from the abnormal cerebral speech. In principle, whether pathological changes, however, are manifested by a change in the intensity of the signal on MRI images. Here we will look at the main reasons for the "bіlih plyam" on magnetic resonance imaging.

1) Perivascular spaces of Virkhov-Robin, stink criblury. What is the perivascular space? Tse skuchennya rіdini vzdovzh vessel, scho to permeate the brain tissue. In the norm, the stench may not be noticeable, but if the blood circulation is disturbed, it can expand, calling out the picture of “white dots” on the signs. There is no great clinical significance of the perivascular space, and it often occurs in healthy people. It's true, more often than not, stench is feared by people with a weak judiciary tone.

Numerous expansion of the perivascular space is a frequent sign of MRI, including in young people. This is not a more unsafe camp, which, however, requires consultations of a neurologist.

2) Multiple middle demієlinіnіzatsії with rozsіyanu sclerosis. It’s not safe to be ill, which will require a negaic obstezhennia, that kindness from a neurologist doctor! It is possible to confirm or exclude the diagnosis of rosacea sclerosis or other demyelinating disease by more respectfully analyzing the results of MRI with contrast enhancement, that blood test (zocrema, analysis for oligoclonal antibodies). The pits of pink sclerosis on MRI look different, lower cribri, but it is reliable to have a radiologist with a great experience.

Characteristic for pink sclerosis is the swelling of hyperintense (increased MR-signal) pits - in the white speech of the ventricle walls of the flanks. For confirmation, a consultation with a neurologist is necessary, but it is possible to take the second opinion of a certified neuroradiologist based on MRI images.

3) Multiple "sudine" middles in dyscirculatory encephalopathy. In case of chronically impaired cerebral blood circulation (as a result of atherosclerosis, hypertension, cervical osteochondrosis, etc.) in the white speech of the brain, there are also spots near the white dots or spots. They may have different names, including gliosis and leukoaraiosis. In most cases, it is possible to treat these types of pink sclerosis for rozashuvannya, due to the accumulation of contrasting speech and other signs. It's a pity, sometimes there is a difference between sclerosis and dyscirculatory encephalopathy for MRI is even more difficult! In such situations, additional obstezhennia, blood tests, and, if possible, a repeated revision of the MRI from the knowledge of an informed radiologist are needed.

Rossiya sclerosis chi dyscirculatory encephalopathy (DEP)? In a number of ways, the analysis of MRI symptoms without a deep knowledge of neuroradiology does not allow a reliable differentiation of patients.

THERE WERE FLASHES ON THE MRI OF COLD

In other cases, patients who underwent MRI of the ridge, snorted on the ridges with whips. Blame natural nutrition, which stench is deluded and naskilki is unsafe.

1) Hemangioma of the ridge. Solitary or multiple hemangiomas in the ridges are streaked in four patients, and for the presence of deformation of the ridges do not carry any kind of insecurity and do not detract from increased respect. However, on the signs of pregnancy, they look bright and in T1 mode, and in T2 mode - the same sign of fatty substitution of hemangiomas (angiolipoma, lipogemangioma) is the most friendly option.

Yaskrava plyama on the ridge - a typical picture of hemangioma. Tse dobryakіsna svіta, like not є pravzhnoy puffy.

3) Metastases in backbones.- Not a rare camp in oncology of the prostate, ovary or. Therefore, light or dark patches on the MRI of the ridge can be confused by the evil sights of swelling with metastases. , fatty dystrophy or brushes can be a number of signs - a clear signal in the mode of fat induction, accumulation of contrasting speech, ruminating or swelling of the cortical ball, soft tissue components along the contours of the ridge. Sometimes such a differential diagnosis can become very complex and will require a glance of an experienced radiologist.

Dark patches on the MRI of the ridge - metastases to cancer of the anterior ridge in a young man. Consultation of an experienced specialist is required.

2) Adipose degeneration and swelling of the cystic brain. Changes in backbones with osteochondrosis - degenerative-dystrophic disease of interspinal discs - are classified as Modic (Modic). The fallow type of changes in the sidial ridges (bruising, fatty infiltration and osteosclerosis) are seen in the Modic 1, Modic 2 and Modic 3 types. When deciphering the signs, it is important not to confuse these changes with metastases.

DRUGA DUMKA ON MRI

To learn more about the doctors in folded hips, they go to the ranks of colleagues, showing them MRI signs with a method to take away a thought from a friend. You can’t know everything, and sometimes you need an additional thought of a high fahivtsya. For these purposes, Russia has created a National teleradiological measure - a system for exchanging medical data, for which you can take expert advice on the results of MRI, CT, PET and other current conditions. Accredited radiologists from specialized centers in Moscow and St. Petersburg, such as the Institute of the Human Brain or the Viyskovo-Medical Academy, carry out a recurrent diagnosis of the overlays of signs and form an expert visnovok. If you are a person, visiting the website of the organization, you can take the decryption of the MRI or CT of the brain, or take the official visa with the signature of the specialist.

In case of suspected pathology of the brain, doctors assign different diagnostic tests to their patients. One of them is MRI. After the procedure, the physicians obtain a ball-and-socket image of the organ. Let the doctor analyze all the data and store the visnovok. Correct deciphering of the MRI of the brain allows you to quickly and adequately interpret. In case of any otrimannya, the result of the follow-up is to complete the folding process for the prepared person. Yogo building to spend less qualifications of a physician.

Informative and precise methods of obstruction of the brain are not so rich

In these articles you recognize:

Who is responsible for deciphering the MRI

Magnetic tomography allows you to take the results of looking at simple signs, as well as in 3D format. In addition, you can record data on a smart phone. Dosledzhennya carry out a doctor of higher specialization - a radiologist. Then the patient goes to the radiologist, who will decipher the data.

Trivality of the birth of a number of patients. Sound deciphering takes two to three days.

For the whole hour, the doctor takes the patient's documents, analyzes the MRI data, digitizes the film, transforming it into pictures. The results are described on paper, and it is less likely to put vysnovok as an example. At private medical institutions, data is deciphered more shvidshe. After an MRI of the brain, a visnovok (result) is seen on the same day.

Deciphering the MRI of the brain may be of great importance when making a diagnosis

Which parameters are evaluated

Patients are prescribed the procedure for suspected pathologies. The results of the MRI procedure for the brain, help the doctor to make the correct diagnosis. Dosledzhennya allows to reveal the attachment of pathology, as if the patient was not disturbed.

Under an hour I look around the MRI signs, the shape is assessed, and the symmetry of the brain is observed. Let's sweat it out, and there was speech and speech and their speech. When clarified first, the doctor suspects pathology. If a patient is to undergo a tomography with contrast, then a medical practitioner can evaluate the vessels and develop a new development at the early stages of their development. Zavdyaks of the new modern tomographs are given to signify even insignificant processes of the pathological state, the shards of the equipment of the building work and even the smallest of sights.

In case of assessment of the nervous system, it is important to analyze not only the skull, the shells of the brain, but also the peripheral endings in the lungs, the organs of the eye, the shards can be directly injected into the camp, the correct practice of the central nervous system.

Modern MRI devices give even more accurate results

What can be the norm on MRI

After the tomography on the pictures one can see fabrics, which are brightened, as well as darkened. Cerebral rіdini rise up, like strings, like light-gray vistas. Inner musculoskeletal fabrics on the images are black, and other fabrics are gray.

When the image is taken, the doctor looks at the injury to the head of the brain. Their contours are equal, rounded. In the MRI norm, vikonan on the brain, it is not guilty to show "vip'yachuvannya" or, on the contrary, to squeeze in from whatever side. The structure of the brain tissues is also being developed. Diffuse, as well as mid-range changes in a normal state are not to blame. We'll let the doctor evaluate the shlunochkovu system. Revision is important as a change, and expansion in any manifestations.

MRI with contrast allows the medical practitioner to judge. If the stinks developed correctly, then the speech should be introduced to remember them equally. This preparation helps to take clear, precise signs, so that it is much easier to decipher.

For the need to vaccinate vessels, an MRI with contrast is performed

What changes are indicated in case of various pathologies

At the guidance below the table, the guidance is changed, as they appear for additional help in the development of various ailments.

Pathology	Change on the removed image
Rose sclerosis.	The light zones are roamed near the mіstsі, where there was a speech. Such a flame may be more than one, but sometimes there are dozens of them. When deciphering the sign, the doctor is guilty of differentiating the autoimmune pathology from cancer.
Sickness of Huntington.	In the structures of the brain, the middle parts of the tails of the nuclei are visible (a paired structure, which is part of a swarthy body).
Gliosis.	In the area of white speech, there are mid-sized denunciations.
Aneurysm of the vessels.	The tinted vessel walls are being cut.
Pukhlin.	Kindly rozryznyayutsya about'mnі osvіti (one chi kіlka), yakі zmіshchuyut normal structure of the brain. Dobroyakіsna puhlin vіdrіznyаєє clear boundaries, zloіakіsnі there are no such contours.
Stroke.	When damaged by a sign, a bright flame is remembered. And at the time of the procedure, due to the need for contrast, there is a decrease in blood flow. In case of hemorrhagic stroke, vessels are opened, which look like black empty vessels. Along the perimeter one can see ring-like smuga.

The drug can reveal Alzheimer's syndrome, pathologies of measles, traumas, clogged muscles and damage to the blood circulation.

Change with puffins

The new establishment for the help of MRI is much easier. On the signs, the stench looks different, fallow like a new creation:

Astrocytoma. Tse evil newborns are most often diagnosed in skronevy or frontal divisions. There are no clear boundaries, as if the gap is lower, lower in tissues that are not damaged by pathology. Such resolutions do not “take in” contrasting speech.

Glioblastoma looks like this

Oligodendroglioma. It develops in the frontal part or the crown of the head. Newly created maє clear contours. This width is lower, lower in normal tissue.
Ependymoma. It is most likely to be settled in chicks. Tse zlojakіsna osvita, as it develops to do it properly. On the signs, it shows up as a round-shaped arboretum. Maє clear contours.
Glioblastoma. Zloyakіsna puhlin іz negative naslіdkami. Tse rounded illumination with clear contours.
Meningioma. You can blame it on any area of the brain membrane. Її a characteristic manifestation is a strong bulge, which will make it bigger, lower without a middle new creation.

The number of different fluffs of qualifications of the doctor can be easily distinguished on the signs.

Ependymoma on MRI

Wad marks on MRI

On the signs of tomography, there may be a wadi, which is the type of people. The technique helps the doctor to assess the nature of the disease, the localization of the anomaly and the spread. On the images, one can clearly see the defects of the skull, the swelling of the shell of the brain, the hand, the change in the cerebellum, the change or the increase in the number of teeth, the expansion of the slit between the pimples and other changes. Must stink to lie in the form of a defect and a pathological state.

Injuries on MRI

In case of head injuries, tomography shows the presence of a lesion, in which no hematoma and axonal lesion were formed. In addition, the doctor can recognize an injury that has become a long time ago (post-traumatic changes). Deyaki see hematomas may have a crescent shape and fuzzy borders.

The level of intensity of the signal, which is seen in hematomas, is rich in what to lie in, in addition, the injury has long been removed.

In the first two or three days after the shock, on some types of images, you can see normal fermentation, and on the others - hypointense. If the trauma happened two days ago, then the picture changes - there is a hyperechoic oblyamivka. Three hours later, the signal from the hematoma becomes hyperintense.

In this video, you will find a lot of inaccurate information about how an MRI is performed and what it shows:

Sudinnі vіdhilennya

I am familiar with the hemangiomi on the signs of the bagatovuzlovі pits. The stench is honed to its kind with kiltsy, it is good to see in the image. The central core of the good accumulates in its own contrasting speech. At any point, the intensity of the transmitted signal is affected. At that very hour in the peripheral ring, the virility is weaker.

Aneurysms are characterized by wide expansion of the arteries. The stench is fusiform in the middle. The stench is not a sign of obvious blood flow.

The results may be inaccurate

Accuracy of depositing according to relevant factors:

The unruliness of the patient. Be-yakі ruhi can lead to the creation of an image on the pictures. In this patient, it is impossible to estimate the size of the rich structures.
Incorrect selection method. In some patients, it is necessary to conduct tomography due to the need for a contrast agent. If you don’t make such a diagnosis, then you won’t be able to confuse the scale of the pathology.

The hour of the follow-up cannot be broken, otherwise the data will not be accurate

Low qualification of a radiologist. The doctor-pochatkivets does not start the building to make the correct description of the MRI of the brain, signify the right or sickness.

Doctors-radiologists should be responsible for the correctness of the preparation by patients, so that before the examination they were not deprived of the usual metal objects.
