COVID-19 (Coronavirus) Update Learn More

Dear Friends and Neighbors,

CentraCare care givers have been working around the clock for more than 20 months to care for you, your families and friends during COVID. We are committed to caring for every Minnesotan who needs us, and nothing will prevent us from doing so – even during these never-seen-before times.

The challenge of providing this level of care is that our hospital beds are often full. ERs in all of our hospitals are packed. And our clinical teams are exhausted. Early in the pandemic, our community stepped up in amazing ways to help us. We ask that you again join us in fighting this pandemic together.

How can you help?

  • Please get your COVID vaccines and booster shots. They are proven safe and effective in reducing COVID illness, keeping people out of the hospital, and preventing death.
  • If your situation is not an emergency, please use other care options, including:
  • If this is a medical emergency, call 9-1-1, or visit the ER.

Together, we can do this. Thank you for your support.

Gated Blood Pool Study (MUGA Scan)

Purpose of the Test

This test evaluates the function of the left ventricle of the heart. It will look at the motion of your left ventricle and the amount of blood it can squeeze out with each beat. The test results will help your doctor decide the best treatment for you.

Patient Instructions


  • There are no special preparations needed for this test.


  • Take prescribed medicines unless told not to by your doctor.


  • Wear normal street clothes.

The Test

  • The test takes place in Nuclear Cardiology at the CentraCare Heart & Vascular Center.
  • We will take a small blood sample through a vein in your arm using an intravenous (IV) port.
  • We will label the red blood cells found in this sample with a small amount of radioactivity.
  • We will wait 20 minutes and then reinject your radio-labeled blood into your vein through your IV.
  • You will then lie down on a table.
  • We will attach three electrodes to your chest.
  • We will take two images of your heart with a gamma camera. Each picture will take 15 minutes.
  • The whole test may take 1 to 2 hours.

If you have any questions, please call CentraCare Heart & Vascular Center at 320-656-7020 or 800-448-3455.
