During the past three decades, the most rapidly growing areas of nuclear cardiology have been stress myocardial perfusion imaging single photon emission computed tomography (MPI SPECT) and positron emission tomography (PET) for the diagnosis and prognosis of patients with known or suspected coronary artery disease (CAD).

A stress ECG has a relatively low sensitivity and specificity. MPI is both more sensitive and specific than an exercise ECG for diagnosing CAD. Maximal benefit is observed in patients with intermediate probability of the disease, and in those with non-diagnostic ECGs.
