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.
If:
– disturbed by constant or acute headaches;
– there is a periodic or constant noise in the ears;
– There is weakness and numbness at the extremities.
– there is a deterioration of memory;
Occasionally, fainting can occur
– The person is confused;
– There was a craniocerebral injury.
– you need to find out the cause of seizures.
Contrast-enhanced MRI of the brain
In order to see the brain more clearly, a contrast is used, which is introduced into the human body. Thanks to the introduction of the dye, tumors and other pathological formations can be diagnosed, and their size, structure and contours can be studied in more detail.
Contraindications to Use
MRI of the brain can be the most safest, but it is not recommended for everyone.
Also, it is worth quitting MRIs when:
– pregnancy;
– claustrophobia;
– The presence of cochlear implant;
– 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 has been placed on the table, a device that sends and receives radio waves is attached to the head. 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.
