title: Annual oration 1989: bring out your barium.
abstract: A critical review of the use of barium examinations of the gastrointestinal tract compared with endoscopy provides evidence of a valid role for barium studies in contemporary radiology. It is concluded that there is no clinical, scientific, or economic justification for the wholesale replacement of barium radiology by endoscopy.
