Gastrointestinal Radiology

Gastrointestinal radiology has expanded its scope beyond conventional abdominal radiography, barium studies, and cholecystography. Ultrasonography allows imaging of abdominal organs and the intestine without the use of radiation. Tomography now allows comprehensive assessment of abdominal and pelvic inflammatory and infectious processes, obstruction, tumor detection and staging, and display of vasculature and blunt trauma effects that were not possible 50 years ago.  Barium enema with air contrast may be used to examining the colon to assess symptoms, including: a recent change in bowel habits, abdominal pain or rectal bleeding. Compared to a barium enema, the air contrast examination offers increased sensitivity for the detection of polyps and small masses.
