MUGA Heart Scan
Evaluation of Cardiac Function with Radionuclide Ventriculography – MUGA
Radionuclide ventriculography is a non-invasive study, which provides information about the pumping function of the heart. In patients with coronary artery disease, and in those who have had a heart attack, the assessment of the pumping function of the heart (also known as the ejection fraction) is essential in the prediction of both long-term and short-term survival.
A small dose of an imaging agent is injected into the blood stream and pictures of the four chambers of the heart are taken using a special camera (gamma camera). These techniques can also provide information about the function of the valves of the heart, the integrity of all the cardiac chambers, and can be used to monitor the effect of different drugs on the heart muscle (in patients with cancer who are treated with chemotherapy). The evaluation of cardiac function with radionuclide ventriculography is accurate and non-invasive and continues to play a critical role in predicting outcomes in patients with heart disease.
