Multi-Gated Acquisition (MUGA) of Heart

CT Control

In order to better serve our referring physicians and their patients, Nebraska Advanced Radiology is in the process of expanding the services they currently offer. The Multi-Gated Acquisition (MUGA) of Heart is a new service offered by the clinic.



The Multi-Gated Acquisition (MUGA) of the Heart is an extremely useful noninvasive tool for assessing the function of the heart. From the test, the MUGA scan produces a moving image of the beating heart; which is then used to determine the health of cardiac ventricles.

The MUGA of the Heart procedure is especially important post-chemotherapy, and calculates the function of the heart’s left ventricle.

According to Medical-Dictionary (The Free Dictionary), MUGA of the Heart procedures are commonly used to test patients:

  • With known or suspected coronary artery disease, to diagnose the disease and predict outcomes.
  • With lesions in their heart valves.
  • Who have recently had a heart attack, to assess damage to heart tissue and predict the likelihood of future cardiac events.
  • With congestive heart failure.
  • Who have undergone percutaneous transluminal coronary angioplasty, coronary artery bypass graft surgery, or medical therapy, to assess the efficacy of the treatment.
  • With low cardiac output after open-heart surgery.
  • Who are undergoing chemotherapy.
