Key points

  • A MUGA scan is a test that uses radioactive material to help take pictures of the blood flowing through the heart.
  • The preparation and the scan are done in the hospital. The test takes about 2.5 hours in total to do.
  • Because a child must stay still for about 30 minutes, some children need to be sedated for the test.
  • The scan does not hurt, but children will have to get a needle.
  • The amount of radioactive material used in the scan is very small and will not harm your child.
