PATIENT RADIATION-DOSES FROM ENTEROCLYSIS EXAMINATIONS

Data relating to patient dose have been acquired for enteroclysis exam inations (small bowel enemas) performed at the John Radcliffe Hospital , Oxford, on 23 adult patients. Dose-area products, fluoroscopy times and the number of radiographs taken are used to compare the examinatio n procedure at the John Radcliffe Hospital with enteroclysis and bariu m follow-throughs performed elsewhere. The mean dose-area product for the 23 examinations was 6.8 Gy cm(2) and the mean effective dose was e stimated to be 1.5 mSv. These doses are intermediate between those ari sing from barium meals and barium enemas performed in the same room.
