The modern non-contact method of brain research is MRI of the Brain. It uses radio waves and a magnetic field to transmit a signal to the computer that allows you to assess the brain’s state. 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?
An MRI of the brain can be used to confirm or detect a variety of diseases. During an MRI examination, the doctor can see a detailed image of your brain and assess its condition.

Contrast-enhanced MRI (MRI) of the brain
In order to see the brain more clearly, a contrast is used, which is introduced into the human 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.
It is also worth giving up MRI when:
– pregnancy;
– claustrophobia;

– installed crowns or braces.
How is the MRI examination
The preparation is the first step in the examination. It is important to take out all metal objects from the phone and then remove it.
After the patient has been placed on the table, a device that sends and receives radio waves is attached to the head. MRI is performed for 30-60 minutes, depending on the department and the presence of contrast in the body.
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.
