Cardiac Nuclear Imaging

Coronary angiography is the gold standard for diagnosis of coronary artery disease, which primarily documents the anatomic presence of significant stenosis. Cardiac nuclear imaging tests have been developed to provide perfusion data. Single photon emission computed tomography (SPECT) uses a radioactive tracer and gamma camera to obtain 3-dimensional images of tracer uptake, and areas of poor uptake are associated with abnormal levels of perfusion. Positron emission tomography (PET) scanners are also used with a radiotracer, and are felt by some to provide better image resolution in heavier patients and those with dense breast tissue.
