Positron Emission Tomography (PET) scans, are a type of nuclear medicine imaging that can be used to map the brain. The scan uses very small amounts of radioactive material, usually injected, to diagnose and determine the severity of a disease and exclude others. Most PET scans are performed on instruments that are combined PET and Computed Tomography (CT) scanners. This allows the information from two different exams to be correlated and interpreted on one image.
