Fluoroscopic GI studies

Procedures → Thorax and Abdomen

Five named studies each carry their own prep, their own key projection, and their own safety rule, and the registry tests all three. The highest-yield items here are the ones where a *position* has a specific job: which upper GI projection shows the retrogastric space, which one fills the duodenal bulb with air instead of barium, and why the RAO rotation is a range rather than a number.
