This document provides a summary of radiology techniques and findings related to the digestive system. It discusses various imaging modalities including plain radiography, barium studies, CT, MRI and US. It describes the normal anatomy and appearances of the esophagus, stomach, small intestine and large intestine on different exams. It also reviews common pathologies like cancers, ulcers, polyps, intestinal obstructions and how they present radiographically.
