<unk>  (or cardiac positron emission tomography) is a form of diagnostic imaging in which the presence of heart disease is evaluated using a<unk>  scanner. Intravenous injection of a radiotracer is performed as part of the scan. Commonly used radiotracers are Rubidium-82, Nitrogen-13 ammonia and Oxygen-15 water.<unk>  scan can assess both blood flow and metabolism accurately. In patients with blocked coronaries,<unk>  scan can influence the choice between bypass surgery and angioplasty. More importantly, it can be used to predict whether depressed heart function can improve after revascularization. __TOC__
