The impact of a physician assistant in diagnostic radiology [PA-DR] on the delivery of diagnostic radiologic clincial services.

A program to train highly selected, experienced radiologic technologists to become Physician Assistants in Diagnostic Radiology [PA-DRs] was initiated at the University of Kentucky Medical Center in 1970. The initial postgraduate year of employment in several different radiologic environments for the first twelve trainees has been evaluated. Their work activities, including examinations that otherwise would have been performed by a radiologist and the number of radiographs screened for evidence of diseases, were analyzed. Studies during their training show they perform these activities accurately. Lastly, the economic impact of PA-DRs and their acceptability to patients and other professionals were evaluated. The PA-DRs spent a majority of their time in activities for which they were trained. Calculated yearly "earnings" of the PA-DRs averaged +31,164. Their salaries ranged +18-25,000. Each PA-DR averaged saving 34% of the employing radiologist's time. They were well accepted by professional colleagues and patients.

Control of experimental traumatic hepatic hemorrhage by transcatheter embolization.

The feasibility of control of traumatic hepatic hemorrhage by angiographic transcatheter embolization was investigated. Bleeding sites were created in the livers of each of twelve dogs, and the hepatic artery was occluded with Gelfoam. Successful control of bleeding was demonstrated by postembolization angiography in all twelve animals. Initial elevations in alkaline phosphatase and serum glutamic pyruvic transaminase values returned to their baseline in four weeks. Recanalization of the hepatic artery in the five surviving animals was shown by follow-up angiograms. Transcatheter embolic control of traumatic hepatic hemorrhage may be a useful adjunct to surgical therapy.
