Location, location: Barium swallow is what it sounds like: swallow barium, shows up on xray film; looks at esophagus, stomach, upper small bowel (duodenum) if done as upper GI series. No prep, empty stomach. Barium enema looks at the colon (not so good for the rectum). After prep to clean colon, barium (with or without air for contrast) pumped into colon to get an outline on xray.
