A MUGA scan may be done while the patient is at rest and again with stress. The resting study is usually performed to obtain the ejection fraction of the right and left ventricles, evaluate the left ventricular regional wall motion, assess the effects...
of cardiotoxic drugs (i.e., chemotherapy), and differentiate the cause of shortness of breath (pulmonary vs. cardiac). Ejection fraction and wall motion are also important measurements made during a stress study, but the stress study is performed primarily to detect coronary artery disease and evaluate angina.

Other Information
A MUGA scan (Multi Gated Acquisition Scan) is a nuclear medicine test to evaluate the function of the heart ventricles. It is also called Radionuclide Angiography. It provides a movie-like image of the beating heart, and allows the doctor to determine the health of the heart’s major pumping chambers. The advantages of MUGA is that it is more accurate than an echocardiogram and it is non-invasive.
