For patients with epilepsy a PET scan is used to localize the part of the brain that is causing the seizure activity. There are various PET tracers to measure glucose, serotonin and oxygen metabolism, cerebral blood flow and receptor binding in epilepsy. Imaging brain glucose metabolism with 18Fluoro-2-deoxyglucose (FDG) PET is the most commonly utilized technique in routine clinical practice (1).
