What is a Nuclear Cardiac Scan?

A Nuclear Cardiac Scan is a test that uses a radioactive substance, known as a tracer, to produce images of the heart muscle. When combined with a stress test, the Nuclear Cardiac Scan helps determine if areas of the heart are not receiving enough blood.

The stress Nuclear Cardiac Scan is especially useful in diagnosing coronary heart disease, the presence of blockages in the coronary arteries (the vessels that supply oxygen-rich blood to the heart muscle).
