Who conducts the interpretation of the results of MRI of the brain

1 Types of tomography

Magnetic resonance imaging allows you to see all the pathological processes occurring in the brain, thereby greatly facilitating the diagnosis of many dangerous diseases. Tomography is considered an absolutely safe procedure, therefore it can be performed as often as necessary.

The tomograph sees absolutely all soft tissues and vessels, but not bones. This is due to the fact that they contain a large amount of calcium. To date, there are two types of magnetic resonance imaging of the brain. Depending on the alleged disease, the doctor may prescribe the first or second type. But if necessary, 2 studies can be assigned immediately.

Computer tomography of cerebral vessels is able to determine the presence or absence of plaques, to detect thromboses, aneurysms, and other abnormalities that are associated with impaired cerebral vascular activity. As a rule, as a result of such a study, all the vessels are thoroughly inspected, which makes it possible to determine even minor violations.

The total magnetic resonance imaging of the brain is able to see absolutely all tissues. With its help it is easy to determine the location of the lesion with strokes, the tissues that were damaged as a result of injuries. But the main thing is that contrast tomography of this type can diagnose neoplasms in the brain.

2 How is the diagnosis of

interpreted? The interpretation of the MRI of the brain should only be performed by an experienced physician.

The doctor, who is responsible for the very procedure of tomography, does not do this. After all, you need to understand the anatomy of the brain well, in order to perfectly compare the findings with those that are considered the norm for all people.

So, first, the radiologist should take pictures of the brain. Ideally, they should be 4. This is the upper, anterior and lateral parts of the brain. After that, the doctor should place all the pictures next to each other under good lighting. Usually for this purpose special wall glasses are used in the clinic, which clearly shine through the pictures.

The brain itself on the film is gray. Brooks between individual convolutions are cerebral fluid. In order to understand whether these components are OK, the doctor compares the obtained photos with anatomically correct images, having normal pictures with pictures of the patient in the immediate vicinity.

It is necessary to determine separately the temporal lobes and the cortex of the brain on the obtained picture. This is due to the fact that some mental pathologies are associated with changes in the cerebral cortex, while the observed inconsistencies in the temporal lobes will not be related to certain diseases.

The main thing in decoding MRI is to reveal inconsistencies with anatomically correct image by colors, shapes and sizes. And than these discrepancies will be more significant, the more serious the problem lies in wait for the patient. Strongly different from healthy areas of the brain can detect even an inexperienced doctor. But minor differences, which usually indicate only the initial stage of development of a particular disease, is not so easy to catch, if there is no experience and knowledge.

3 Features of the image

If the image of the brain clearly shows almost white spots, which differ from all other tissues with special brightness, this indicates neoplasms in the brain. Such tumors can be either benign or malignant. But this can already be determined accurately from other analyzes. It is usually required in detecting neoplasms and further from time to time to do an MRI to monitor the dynamics of tumor growth.

In the event that MRI was done without contrast, there is a high probability that such a fatal disease as brain cancer will be confused with harmless for the patient's life pathology. The better the contrast, the more accurate the diagnosis can be based on MRI.Sometimes even by contrast, experienced doctors can not clearly determine what is actually going on in the patient's brain. What can we say about inexperienced people who, while looking at the pictures, try to diagnose themselves.

Also dangerous is the leakage of cerebral fluid. If there are much darker spots on the places of the channels through which this liquid passes, then it means that there was a leak to the brain after all. Usually this happens after complex head injuries and can lead to mental disorders and other very serious diseases of organ systems. These spots have an asymmetrical shape. A healthy person in the picture may also have similar spots, but they will be symmetrical and small.

In some cases, the pathology of the brain is confused with damage to the bones of the skull. Often this happens when the MRI is done immediately after the injury. In this case, a cracked or broken bone prevents the tomograph from recreating an ideal picture of the human brain. Even more difficult, if as a result of the injury, the soft bone tissue was partially mixed with the cerebral fluid. Then you need a more thorough study to establish an accurate diagnosis.

Although deciphering MRI of the brain is very interesting and not so difficult in theory, in practice in the case of a serious study this should be done by an experienced doctor. Only trained specialists are able to deliver the most accurate diagnosis. After all, often even qualified doctors do not have the same opinion, as a result, a collegial study of the images is required.
