A qSPECT brain image requires a small amount of radioactive material called a tracer, which is given through a vein in the arm. This tracer travels through your blood stream and is absorbed by the brain and your body. The absorption process usually takes about 20 minutes or more.
After the tracer is absorbed, you will be escorted into the scanning room where you will lie on a table which slides into the SPECT machine. The SPECT machine detects signals from the radioactive tracer and a computer changes these signals into a 3-D picture that are evaluated by a highly trained radiologist. CereScan scanners give the best image quality available today and utilize an open, non-claustrophobic design for your comfort. A typical qSPECT brain image scan takes 20 minutes or more.
