WebSPECT is a nuclear imaging scan that integrates computed tomography (CT) and a radioactive tracer. The tracer is what allows doctors to see how blood flows to tissues and organs. Before the SPECT scan, a tracer is injected into your bloodstream. The tracer is radiolabeled, meaning it emits gamma rays that can be detected by the CT scanner. WebIctal SPECT testing requires that seizure activity be provoked through reduction of anti-epileptic medications. Video EEG monitoring may also be perform ed.
