WHAT IS A NUCLEAR STRESS TEST?

 

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.

 

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.
