MUGA (Multiple Gated Acquisition)

  • No preparation for the scan is required

This test is useful before & after chemotherapy, and to assess other heart diseases. Useful to investigate left ventricular function, to assess drug effects in patients with LV disorders and to predict prognosis in patients with coronary artery disease. The study can be performed at "rest", or under "stress" conditions to examine LV response to known stress levels. A simple study can generally be completed in about one hour. 

Labeled red blood cells circulating the body are imaged in the left ventricle. At the same time the patient's ECG is used to "gate" the imaging data. The combined data are displayed as a single heart cycle and the left ventricle ejection fraction can be calculated. 

Used to assess:

Heart function Check the size and motion of the left ventricle
