PET scans can assist this surgery because it can show the exact part of the brain responsible for the person’s epilepsy.PET imaging has also been used to assess people with other neurological diseases, including Alzheimer’s disease and Parkinson’s disease, because the images can show areas of the brain that are functioning differently to normal.
