Imaging of the stomach and duodenum.

Problems in the distinction between gastritis and gastric cancer on CT and the evaluation of cancer on endoscopic ultrasonography have been highlighted. Four cases of gastric cancer in Crohn's disease draw attention to this as a disease-related complication. Patient preference for barium upper gastrointestinal study compared with endoscopy has been challenged, as has the reliability of the radiologic diagnosis of duodenitis. CT in peptic ulcer disease is evaluated and there is continued interest for interventional feeding techniques, with two papers on the fluoroscopic placement of nasoenteric tubes.
