MUGA Scan - CAM 733
Multiple-gated acquisition (MUGA) scanning uses radio-labelled red blood cells to scan right and left ventricular images in a cine loop format that is synchronized with the electrocardiogram.
A prior MUGA scan is not an indication for repeat MUGA (if another modality would be suitable, i.e., TTE)
Multiple Gated Acquisition (nuclear scan of ventricular function)
Multiple Gated Acquisition (MUGA) Scan is considered MEDICALLY NECESSARY for the following indications:
It is an expectation that all patients receive care/services from a licensed clinician. All appropriate supporting documentation, including recent pertinent office visit notes, laboratory data, and results of any special testing must be provided. All prior relevant imaging results, and the reason that alternative imaging cannot be performed must be included in the documentation submitted.
Indications for Multiple Gated Acquisition (MUGA) Scan
- To evaluate left ventricular function in a patient with coronary artery disease, valvular heart disease, myocardial disease, or congenital heart disease, in any of the following scenarios:
- When ventricular function is required for management, and transthoracic echocardiography (TTE) or other imaging has proven inadequate (Patel, 2013; Yancy, 2013)
- When there are conflicting results between other testing (i.e., Myocardial Perfusion Imaging and TTE) in the measurement of ejection fraction (EF), and the results of the MUGA will help in the management of the patient
- Prior TTE has demonstrated systolic dysfunction (EF < 50%) and management will change based on the results of the MUGA scan
- In the course of cardiotoxic chemotherapy when TTE images are inadequate to evaluate left ventricular systolic function (Patel, 2013; Plana, 2014; Yancy, 2013; Zamorano, 2016):
- Previous low LV ejection fraction was < 50% and receiving potentially cardiotoxic chemotherapy
- Prior to cardiotoxic chemotherapy, and subsequently for monitoring and follow up. The frequency of testing should be left to the discretion of the ordering physician, but generally no more often than at baseline and every 6 weeks thereafter
All other uses of this technology are investigational and/or unproven and therefore considered NOT MEDICALLY NECESSARY.
