Head MRI is done in the hospital or radiology center. You lie on a narrow table, which slides into a large tunnel-shaped scanner. Some MRI exams require a special dye, called contrast. The dye is usually given before the test through a vein (IV) in your hand or forearm. The dye helps the radiologist see certain areas more clearly. During the MRI, the person who operates the machine watches you from another room.
