Muga/Radionuclide Angiogram

A MUGA or RNA test is a non- invasive diagnostic test used to evaluate the pumping function of the ventricles or lower chambers of your heart.


How should I prepare?

  • There is no special preparation for this test
  • There are no restrictions of food or medication
  • Wear comfortable clothes that can easily be removed


What happens during the test?

  • The test will be explained to you.
  • You will be given an injection of Gluceptate
  • After 30 minutes, you will be given a second intravenous injection- this is a radioactive tracer
  • You will then be attached to an ECG monitor
  • You will be asked to lie on a bed/chair  for 20 to 30 minutes under a Gamma Camera
  • This  camera will take computer generated images of your beating heart
  • The  computer generated images will allow the Nuclear Medicine technologist to make calculations of your Ejection Fraction or how well your heart is pumping
  • This information will be given to your physician to help guide your treatment
