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.
Introduction. RSA is a powerful research technique that is currently being studied at Hospital for Special Surgery (HSS) for joint replacement patients. RSA stands for r adio s tereometric a nalysis, which describes a special way of taking two x-rays from different directions at the same time, creating a âstereoâ image.SA has been used for over 30 years in Europe and for 5 years at Hospital for Special Surgery. The only potential risks come from implantation of the marker beads. 1  The insertion of beads takes an additional 5 to 10 minutes of surgery.
