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?
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.

After the patient is placed on the table, and a device is fixed on the head, which will send and receive radio waves. 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.
