A thallium scan is a test that uses a radioactive substance (known as a tracer) to produce images of the heart muscle. When combined with an exercise test, the thallium scan helps determine if areas of the heart do not receive enough blood.
The exercise thallium test is especially useful in diagnosing coronary artery disease, the presence of blockages in the coronary arteries. These arteries supply oxygen to the heart muscle. Tracers, other than thallium, can be used for this type of scan. Your Baylor Scott & White Cardiology Consultants of Texas doctor will decide if your situation warrants a different type of tracer.
