Myocardial Perfusion PET Stress Test
This exam is also known as a Rubidium PET.
Exercise stress, pharmacological stress testing (Thallium, Sestamibi), vasodilator stress (adenosine, regadenoson), and dobutamine stress have the same preps, but vary in the time it takes to complete the study.
Your doctor has requested a PET Myocardial Perfusion (MP) Stress Test, also called a Rubidium PET. This procedure evaluates the blood flow (perfusion) through the coronary arteries to the heart muscle using a radioactive tracer. The completed exam consists of intravenous access, resting images, a stress test (performed by use of a medication-- no exercise or treadmill), and stress imaging. Our team of cardiac imaging physicians, nurse practitioners, technologists, and ECG technologists is headed by Daniel Berman, MD, chief of Cardiac Imaging and Nuclear Cardiology.
