Types of Brain Scans. Scans generate images of the brain for the purpose of diagnosing tumors. They take the place of x-rays, which do not show tumors located behind the bones of the skull or spine. The most common scans for diagnosis and follow-up are magnetic resonance imaging (MRI) and computerized tomography (CT). Certain types of brain scans use a special dye, called contrast, to help areas of interest show up better. Contrast dye is usually injected into the body before the scan starts. With the exception of those requiring an injection of contrast dye, scans are relatively painlessâlike getting a picture taken.
