A form of a SPECT test called subtraction ictal SPECT coregistered to magnetic resonance imaging (SISCOM) may provide even more-detailed results. The tracer is injected into a vein to create a detailed, 3D map of the blood flow in the brain during a seizure. A SPECT test uses a small amount of low-dose radioactive tracer. Single-photon emission computerized tomography (SPECT).PET scans can uncover areas of the brain where the seizure began. This helps visualize active areas of the brain.
