The radiology assistant: a contrarian's view.

Recent and rapid increases in the utilization of diagnostic imaging have not been matched by concomitant additions to the supply of radiologists and radiology technologists. One proposal to alleviate an expected worsening of this emerging workforce crisis is to create a new job category, the radiology assistant (RA), encompassing a roster of enhanced capabilities that would allow the radiologists to divest themselves of some of their non-interpretative duties with respect to the performance of imaging tests. Through the collaborative efforts of the American College of Radiology and the American Society of Radiology Technologists a nationally recognized, baccalaureate-level curriculum has been designed for the training of RAs. A centerpiece of the curriculum is instruction in fluoroscopy. However, examinations of the GI tract by fluoroscopy are rapidly declining in frequency, raising doubt about the enhanced value an RA would bring to a radiology practice in the near future and worries about encroachment on the range of radiologists' responsibilities over the long term.
