SPECT

Submitted by Carol Ireland

Single Photon Emission Computerised Tomography. A diagnostic scan where a radioactive isotope is injected to determine blood flow within the rain. During a seizure there is increased blood flow in the region of the brain where a seizure begins. Inbetween seizures, the bloodflow is reduced in this area. The SPECT is performed on people with epilepsy who are working up for possible surgery for epilepsy. Scanning can help determine the origin of the seizure.
