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.
In some cases, MRI diagnosis is needed to confirm the diagnosis or to refute it.
– disturbed by constant or acute headaches;

– There is weakness and numbness at the extremities.
– There is a decline in memory.
Occasionally, fainting can occur
– The person is confused;
– There was a craniocerebral injury.
You need to determine the cause of seizures.
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.
It is also worth giving up MRI when:
– The presence of cochlear implant;
– decompensated heart failure;
– The presence of tattoos that are made from metal;
– installed crowns or braces.
What is an MRI exam?
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. 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.
