A nuclear stress test is a specific type of cardiac stress test that uses radioactive material to evaluate blood flow to the heart. Gamma cameras track and record the tracer’s radiation, producing images of the blood flow. By combining these technologies with exercise, technicians can discover potential health issues while the body is active or resting.

1. Purpose

Nuclear stress tests are necessary when a standard cardiac stress test cannot determine the cause of symptoms like chest pain or shortness of breath. In some cases, doctors use nuclear stress tests to guide treatments for certain heart conditions. Performing this test allows health professionals to determine how well the heart works, how large it is, what treatment is necessary, and what to expect in terms of future heart problems.
