MRI is a magnetic resonance imaging of the head, which is a non-invasive examination that helps to more accurately establish the diagnosis and prescribe the right treatment.
Principle of examination
The essence of MRI is the use of high-power magnetic fields and accurate pulses transmitted to the computer, resulting in an accurate image of all parts of the brain:
- soft tissues;
- bone tissue;
- other structures of the body of the head inside.
The result of such an analysis can be studied on a monitor, displayed on a large screen using a projector, sent by e-mail and printed. The method is absolutely safe, because the substances used, for example, when X-ray is not needed.
Detailing images, namely imaginary sections in separate places, allow doctors to accurately and accurately detect any deviations in certain organs. Modern medical practice considers MRI to be the most accurate and sensitive method of viewing organs and determining the ailments.
What pathologies can be detected with MRI?
When issuing a referral to the MRI of the cerebral vessels, namely, what sections or details are shown, the attending physician indicates a preliminary diagnosis and what departments are worth paying attention to. So, here's what diseases shows MRI of the brain:
- stroke ;
- meningitis;
- encephalitis;
- neoplasms;
- defects in development;
- causes of epilepsy;
- injuries;
- disorders of the ear and eyes;
- Vascular pathology;
- multiple sclerosis and other ailments.
MRI of the brain with contrast, in more detail shows what happens in the vessels of the head. A lot of pathologies are associated with vasoconstriction or thrombosis in them. It is done by introducing a special substance into the vein, which reaches the blood vessels of the head and precisely reflects the clinical picture.
And, for example, an MRI of the brain without using contrast perfectly shows that it suffered from a bruise, reveals the presence of cysts, bruises and other problems.
In general, the type of test to be prescribed depends on the patient's complaints. If there are no obvious pathologies, and the patient complains of frequent headaches, impaired sensitivity, loss of coordination, then first an overview MRI of the brain should be performed, and she will show what and how to be more carefully examined.
With epilepsy MRI of the brain, on the contrary, it shows what should be excluded: tumors, abnormalities in the structure of blood vessels and organs, and other ailments.
How does the procedure work?
The duration of the study is up to half an hour, in case of using contrast - up to 45 minutes. By itself, staying in the device is absolutely safe, however, being inside, the patient may experience discomfort. All this time should lie still, because any movement is able to distort the result and give the wrong image.
During the MRI, the patient is alone in the room, but the lab technician can talk to him using a special communication.
There are no contraindications, as such, to the procedure,
- Warn about pregnancy.
- Remove metal jewelry, crowns, hairpins and other items.
As a conclusion, it can be said that the appearance of magnetic resonance imaging has become a real breakthrough in the definition of ailments and their causes. Therefore, in order to find out whether an MRI will show, for example, a brain tumor, one can not doubt: it will show, and not only it. This method is able to determine a lot of diseases, and as we know, the correct diagnosis is already fifty percent successful recovery.
