Nuclear Cardiology

Nuclear cardiology is the study of the heart using small amounts of radioactive tracers. It allows us to study the function of the heart non-invasively (without inserting any instruments into the heart itself).

The most commonly used test in nuclear cardiology is called myocardial perfusion imaging. It is a diagnostic tool that is often used for the detection of coronary artery disease (narrowing of the heart arteries).

Myocardial perfusion imaging is a form of stress test which makes use of myocardial perfusion tracers and gamma camera imaging methods to assess the adequacy of blood flow to the heart, as well as to assess how much of the heart muscle is viable (alive) and how much is scarred and damaged beyond repair after a heart attack.
