Gated Heart Study

About Gated Heart Studies:

Gated heart imaging (MUGA scan) is a well-established, relatively inexpensive and accurate method for evaluating cardiac size, wall motion and function.

The test should not be used for direct evaluation of valve motion, or estimating myocardial thickness. Cardiac Echo Studies are the procedure of choice for assessing these parameters.



  • Assessment of volume, wall motion, and function of LV.


  • The patient's red blood cells are labelled with a radiotracer. 

  • The camera is centred over the cardiac blood pool and imaging of the heart is synchronised with the patient's ECG.

  • Scan time is approximately 30 minutes, the entire procedure takes approximately 1 hour.
