Radiographic scanning in barium examinations of the gastrointestinal tract.

Abstract

The possibility of using radiographic scanning for gastrointestinal studies was evaluated experimentally. Two tubular barium-filled phantoms containing simulated ulcers and polyps were placed in a 25-cm water container, and radiographs made with the conventional technique and scanographic technique were compared. Images obtained with the radiographic scanner were superior in contrast and sharpness. Two-millimeter polyps could be easily detected in the larger phantom. Due to improved latitude the larger phantom could be adequately penetrated without overexposing the smaller phantom. This was not possible with the standard technique. Best results were obtained with a heavily filtered 140-kVp beam. Radiographic scanning has great promise in barium examinations of the gastrointestinal tract.
