MUGA/RIVG (Resting Ventriculogram)

What is a MUGA/Resting Ventriculogram?
A MUGA scan is a nuclear medicine study that determines how well your heart is squeezing and pumping. 

Why did the doctor order this scan for me?
This test is usually ordered when a patient has a low ejection fraction, cardiomyopathy, CAD, and/or other heart conditions.  This scan also is used for Mercy Cancer Center patients to evaluate the heart before and/or after chemotherapy.

What do I nee to do to prepare for this scan?
There is no special preparation for this scan. Please bring your insurance card(s), driver's license and co-pay.

What should I expect when I get to the hospital?
You will first need to check in and register at the Radiology Registration desk located past Mercy Gift Shop to the left.  When you register your personal and insurance information will be updated. Once you are registered, you will be asked to sit in the waiting area. A technologist will call you and take you to the Nuclear Medicine area. 

Who will be in the scanning room with me?
Your family is welcome to accompany you during the explanation of the test, but will be asked to return to the waiting room during the actual scan.  A nuclear medicine technologist will perform your scan.

What will I experience during the scan?
The technologist will ask you some questions regarding you medical history and the problems that you are experiencing.  Then the technologist will start an IV in your hand or arm in order to withdraw some of your blood.  This blood then mixes with a radioactive tracer for 30 minutes.  After the blood is done mixing the technologist will give the blood back to you through your IV.  There are no side effects from this injection.  Next, the scan will begin and will take about 40 minutes.  You will be asked to hold still and have your arms raised over your head for the first half of the pictures.

What do I need to do after the scan?
Following your MUGA scan you can return to normal activities. 

When will I get result of the scan?
You will receive your results from your ordering physician.  You may receive a letter, a phone call, or have a follow up appointment with your physician.  If you are unsure of how you will receive your results, please contact your physician's office.
