Use of water or air as oral contrast media for computed tomographic study of the gastric wall: comparison of the two techniques

Abstract

Thirty-four patients with a high suspicion of gastric lesion at endoscopy were studied by two computed tomographic (CT) techniques: one using a gas-producing agent and the other using water as an oral contrast media. Intravenous contrast medium was also given in all patients who underwent the water technique. Final histologic proof was obtained either by endoscopy or at surgery. Both CT techniques detected the wall abnormality in 32 of the 34 patients, and both techniques missed the same lesion in two patients. The water technique showed more gastric wall details and the lesion's limits could be defined more accurately. The acceptance and tolerance of the gas-producing agent was better in severely ill patients than tap water.
