A Muga scan is used to show how efficiently a person's heart functions. It examines how well the bottom chambers of your heart pump blood out into your body.
How is a Muga Scan performed?
An IV will be started by the technologist and some blood will be drawn. This blood will be "tagged" with a small amount of radioactivity while you wait. This tagging process takes about 30 minutes. Your blood is then given back to you through the IV. There are no side effects from this radioactivity.
The technologist will then walk you to the scan room. You will lay on a special camera bed while a series of three images are taken. These images will also take about 30 minutes. Total time for the procedure is about one hour.
How do I prepare for the scan?
Follow the instructions provided by the imaging center when you make your appointment.
- You may need for fast for 4-6 hours before the test. You may also be asked to avoid caffeine and tobacco for up to 24 hours prior to your test.
- Be sure to discuss any medications you are taking with your care team. You may need to stop taking certain medications prior to the scan.
