Nuclear Tests help diagnose heart and coronary artery disease by revealing function, as opposed to other tests that simply show the appearance of bodily organs and structures.
Safe and painless, nuclear testing involves the injection of tiny amounts of radioactive substances into the body, which can then be traced with a special camera and analyzed by computer.
Cardiac SPECT (single photon emission computer tomography) is one of these nuclear diagnostic testing tools. Dr. Diego may obtain a cardiac SPECT scan of the heart at rest, and again when the heart is working hard during the stress test. The advantage of a SPECT scan is that it can show blood flow, muscle contraction, and other actions of the functioning heart. Therefore, the doctor can see abnormalities in blood flow or weaknesses where the heart is laboring to pump enough blood.
