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
