Fast Facts About SPECT

  • SPECT is a nuclear medicine test to detect changes in blood flow in your child’s brain; it can help doctors pinpoint the area deep within your child’s brain that is causing his or her epileptic seizures.
  • This test will be done when your child is admitted to the hospital’s Epilepsy Monitoring Unit (EMU) for epilepsy surgery evaluation.
  • No preparation is needed before the SPECT test.
  • Your child will have an intravenous (IV) line placed prior to the test. A special dye will be injected into the IV to highlight the flow of blood in the brain and a computed tomography (CT) scan will capture an image of the blood flow.
  • Two SPECT scans are needed: One must be done at the onset of a seizure. For that reason, your child may have to stay for several days to as long as 2 weeks in the EMU to wait for a seizure.
  • You will need to stay with your child during his or her entire stay in the EMU, as well as during the SPECT scans, to help identify seizures, since you know your child’s epilepsy best.
  • Because this test uses radiation, women who are pregnant or believe they may be pregnant should not be in the room when SPECT scans are done. In this case, another adult may stay with your child during the scan.
  • Teenage patients who are pregnant or believe they may be pregnant should talk to their doctor before having a SPECT scan. This information will be kept confidential.
