Radiology performed by nonradiologists in the United States: who does what?

Abstract

The general radiology performed by nonradiologists is of a magnitude that easily could be transferred to radiologists, particularly because many unnecessary imaging studies would most likely be eliminated as a result. Such a transfer would reduce costs and probably improve quality but might sometimes decrease patient convenience. However, because many radiologists do not perform coronary angiography and cardiac sonography, a transfer of these responsibilities to radiologists would be problematic and likely to require extensive additional training of radiologists.
