Nuclear stress testing measures blood flow to the heart muscle at rest and during stress using a radioactive substance that creates images of the heart muscle. A nuclear stress test helps to determine which parts of the heart are healthy and function normally and which are not.
A nuclear stress test is helpful in the diagnosis of coronary artery disease, in determining the size and shape of your heart, and in establishing the best treatment plan for other heart disorders, such as arrhythmia.
During the procedure, you will be injected with a small amount of radioactive substance. The doctor then uses a special camera to identify the rays emitted from the substance within the body providing clear images of the heart tissue on a monitor. The doctor will take these images when you are at rest and after exercise.
A nuclear stress test allows doctors to see areas of the heart that have a decreased blood supply. Inadequate blood flow to any part of the heart will be indicated as a light spot on the images.
