Q. What is Multi-gated equilibrium radionuclide angiography?
Multi-gated equilibrium radionuclide angiography (MUGA) is a very accurate method in measuring ejection fraction. Rest and exercise equilibrium radionuclide angiography has been used in conjunction with or as an alternative to thallium scintigraphy in the detection of coronary artery disease. Regional or global abnormal wall motion at rest or during exercise can be accurately delineated with this technique. It is also a powerful predictor of subsequent adverse cardiac event. It is also useful in managing patients with stenotic or regurgitant valvular lesions.
