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 that MRI of brain can be used to assess the health and condition of both soft tissues as well as blood vessels.
What is the best time to have an MRI?
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.

Contrast-enhanced 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.
It is also worth giving up MRI when:
– the presence of cochlear implants;
– decompensated heart failure;
– The presence of tattoos that are made from metal;
Installed crowns and 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 takes many layers-by-layer photographs of the brain and then makes a decision.
