Heart PET scan

Heart nuclear medicine scan; Heart positron emission tomography; Myocardial PET scan

A heart positron emission tomography (PET) scan is an imaging test that uses a radioactive substance called a tracer to look for disease or poor blood flow in the heart.

Unlike magnetic resonance imaging (MRI) and computed tomography (CT), which reveal the structure of and blood flow to and from organs, a PET scan gives more information about how organs and tissues are working.

A heart PET scan can detect whether areas of your heart muscle are receiving enough blood, if there is heart damage or scar tissue in the heart, or if there is a buildup of abnormal substances in the heart muscle.
