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 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?

Contrast-enhanced MRI (MRI) of the brain

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. Depending on the area and whether there is contrast, MRI can take between 30-60 minutes.
The doctor takes many layers-by-layer photographs of the brain and then makes a decision.
