Overview
Chest CT
- Chest CT is done when fluoroscopy is equivocal, and there is persisting suspicion of perforation.
- Signs of chest CT scanning include:[1]
- Pleural or mediastinal fluid
- Pneumomediastinum or pneumothorax
Abdominal CT
- Signs of perforation on abdominal CT scanning include:[2]
- Extraluminal oral contrast
- Free fluid or food collections
- Discontinuity of the intestinal wall
- Localized peritoneal fat stranding
- Bowel wall thickening
- Fistula
- Intra-abdominal abscess
