Cardiac nuclear medicine tests are indicated for individuals with unexplained chest pain or chest pain brought on by exercise (called angina) to permit the early detection of heart disease.
The most common cardiac nuclear medicine procedure, called myocardial perfusion imaging, enables the visualization of blood-flow patterns to the heart walls. The test is important for evaluating the presence of suspected or known coronary artery disease (blockages) as well as the results of previous injury to the heart from a heart attack (myocardial infarction). It also can be done to evaluate the results of bypass surgery or other revascularization procedures designed to restore the blood supply to the heart. Heart-wall movement and overall heart function can be also be evaluated.
