Radionuclide angiography is a nujclear scan (muga scan) used to assess pumping function of the heart. Catheterization is an invasive procedure and muga scan is non-invasive procedure with minimal risk. ...Read more

Other institutions feel the risk of complication from IV contrast outweighs the benefits and do not give IV contrast.
