Nuclear Stress Testing

A nuclear stress test uses radioactive dye to show how well the blood flows into your heart. The test involves injecting the dye then taking images of the heart, at rest and after exertion. A nuclear stress test can be done alone or in conjunction with other tests.

Your family medicine or cardiologist may suggest a nuclear stress test to diagnose coronary artery disease or to find out how well treatment is going for other heart disorders.
