Chest computed tomography (CT) is done when fluoroscopy is equivocal, and there is persisting suspicion of perforation. Signs of perforation on abdominal CT scanning include extraluminal oral contrast, free fluid or food collections, discontinuity of the intestinal wall, localized peritoneal fat stranding, and Bowel wall thickening.
