A CT scan is the test of choice to evaluate for the four types of intracranial hemorrhage (subdural, epidural, intracerebral, or subarachnoid) bleeding in the brain, swelling of the brain during the first 24 to 48 hours after injury, or to detect a skull fracture [4] because it is faster, more cost-effective, and easier to perform than an MRI.
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.
