Cardiac PET

Cardiac PET (or cardiac positron emission tomography) is a form of diagnostic imaging in which the presence of heart disease is evaluated using a PET 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.

Cardiac Pet scan can assess both blood flow and metabolism accurately. In patients with blocked coronaries, Cardiac PET 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.
