1. The stomach is commonly a site of disease in the emergency department patient presenting with epigastric pain.  Although traditionally evaluated with fluoroscopy, gastric emergencies are now more commonly seen on CT. 2. CT technique considerations when evaluating the stomach include the use of positive or neutral contrast as well as the use of arterial and portal venous phase imaging, such as when searching for a source of gastrointestinal bleeding. 3. The emergency radiologist must know the normal appearance of the stomach on CT, along with the typical appearance of infectious, inflammatory, and complications of surgery and/or malignant disease.
