During the resting MUGA, the patient lies stationary, whereas during a stress MUGA, the patient is asked to exercise during the scan. The stress MUGA measures the heart performance during exercise and is usually performed to assess the impact of a suspected coronary artery disease. In some rare cases, a nitroglycerin MUGA may be performed, where nitroglycerin (a vasodilator) is administered prior to the scan.
An RMA (return merchandise authorization) is a numbered authorization provided by a mail-order merchant to permit the return of a product. 1  Most mail-order businesses have a policy concerning returns. Some companies allow only defective products to be returned; others allow any software to be returned if it is unopened.
Report Abuse. An RMA is a return material authorization number. It's a number from the company you're going to send the merchandise back to so they can track it internally. It's not a shipping tracking number and UPS has nothing to do with it. You make sure the RMA number is very visible on he outside of the package so the receiver will know who the package is from and what needs to be done with it. A company can issue a pickup request through UPS. This generates the return label.
