A PET scan (Positron Emission Tomography) is a diagnostic test used in cardiology to check blood flow to the heart. During the test, a small amount of radioactive tracer is injected into a vein, which is not a dye or contrast. A special camera called a PET scanner detects the radiation released by the tracer and creates computer images of the heart. The greatest benefits of a cardiac PET scan are its ability to accurately measure blood flow between the coronary arteries and heart muscle, detect areas of low blood flow in the heart, and identify dead tissue. PET scans are also useful in quantifying myocardial blood flow and assessing myocardial perfusion[1][2][3][4][5].
