Learn how a SPECT scan helps identify where seizures start in the brain.

Key points

  • A SPECT scan is takes pictures of the blood flow in your child's brain during a seizure.
  • The scan takes place during a stay at the epilepsy monitoring unit and has two parts: an ictal scan during a seizure and an interictal scan between seizures.
  • Before an ictal scan, your child's team may lower your child's anti-epileptic drugs for a short time and inject your child with a small amount of radioactive liquid to better show blood flow during a seizure.
  • You may discuss the results of the SPECT scan with your child's doctor about four to six weeks after the test.
