Recent developments in diagnostic radiology of primary and recurrent gastric cancer

To summarize the imaging work-up of gastric carcinoma, the patient should be initially evaluated with a double-contrast UGI series and correlated with endoscopy. Some authors feel that the primary role of UGI is to provide a guide to the endoscopist. The area in question should be biopsied. The role of CT is controversial due to limitations in staging. Some feel that it is an ancillary procedure, as are ultrasound, MRI, and angiography. Exploratory laparotomy is recommended as the diagnostic and therapeutic evaluation of choice. However, CT may prevent surgery in the nonsymptomatic patient with diffuse metastatic disease.
