MULTIPLE GATED AQUISTITION (MUGA) SCAN
About the test:
- A Cardiac MUGA scan is a special type of imaging in which a small amount of radioactive material is injected into a vein and detected by a special camera that creates a movie. The MUGA scan offers additional information about the condition of your heart, including how well the heart is pumping blood and whether there is damage to the heart muscle
What to expect:
- Usually during a MUGA scan, sticky EKG pads are attached to the upper chest and a needle is inserted into an arm vein.
- As the radioactive material moves through the heart chambers and/or heart muscle, a nuclear scanning camera records the heart’s images. Although MUGA scans involve injections of the radioactive material, the total exposure to radiation is limited (usually less that with a chest x-ray).
How to prepare:
- No preparation is necessary. Take you medications as usual.
How long does it take:
- MUGA scan studies usually take about 1 ½ hour
After the test:
- There are no restrictions after the procedure, unless you are advised of precautions at the time of the test.
Exercise MUGA:
- If your scan includes exercise, you should not eat or drink 8 hours prior to the test. Also, wear comfortable clothing and shoes as you will be riding a bicycle while the pictures are being taken.
