A PET (Positron Emission Tomography) scan provides a computer-generated image of the activity of the brain by following the metabolism of glucose. The patient is injected with a small amount of radioactive glucose which is taken up by the brain cells, and the PET scanner detects the radiation emitted by the glucose to create an image of brain activity. CAT (computed axial tomography) scans use X-rays to create images of structures inside the body, EKG (electrocardiogram) is a test to detect heart problems, and fMRI (functional magnetic resonance imaging) measures blood flow to different areas of the brain to detect brain activity.
