MRI of the brain is one of the modern non-contact methods of brain research, which uses a magnetic field and radio waves that transmit a signal to a computer and allow you to assess the state of the brain. It is important to know that MRI of the brain is used to examine both soft tissues and blood vessels for damage or injury, such as a stroke.
When is an MRI scan done?
MRI of the brain is performed to detect or confirm a wide range of diseases. During an MRI examination, the doctor can see a detailed image of your brain and assess its condition.
Sometimes, MRI diagnosis may be required to confirm or refute the diagnosis.

– The person is confused;

Contrast-enhanced MRI (MRI) of the brain
Contrast is used to better see the brain. It is introduced into the body. The dye can be used to diagnose tumors and other diseases, as well as their structure and contours.
Contraindications to Use
MRI of the brain is the safest procedure, but some people do not do it: if they have a pacemaker, a hemostatic clip in the brain or metal implants.
Also, it is worth quitting MRIs when:
– the presence of cochlear implants;
– decompensated heart failure;
– the presence of tattoos created on a metal basis;
Installed crowns and braces
How is the MRI examination
The examination begins with the preparation: it is necessary to remove all metal objects and remove the phone.
After the patient is placed on the table, and a device is fixed on the head, which will send and receive radio waves. Depending on the area and whether there is contrast, MRI can take between 30-60 minutes.
The doctor receives many layer-by-layer images of the brain, on the basis of which he makes a conclusion and confirms or denies the diagnosis.
