Nuclear Cardiology

MUGA

The MUGA scan (Multiple Gated Acquisition scan) is an extremely useful noninvasive tool for assessing the function of the heart when information on blood flow to the heart muscle is not required.  The MUGA scan produces a moving image of the beating heart, and from this image several important features can be determined about the health of the cardiac

Treadmill Stress Test

The treadmill stress test is just that, a stress test entirely done on the treadmill.  Patients are hooked up to an EKG machine for evaluation under exercise conditions. EKG abnormalities relative to cardiac problems can present themselves under exercise or “stress” conditions.

The level of mechanical stress is progressively increased by adjusting the difficulty (steepness of the slope) and speed.

Nuclear Stress Test

The main clinical examination performed in nuclear cardiology is Myocardial Perfusion Imaging (also known as a Nuclear Stress Test). During a nuclear stress test, a small amount of radioactive tracer is injected intravenously. Two injections are administered: under rest conditions and under stress conditions. Stress conditions are obtained by use of treadmill exercise or medications that simulate the effects
