Barium Swallow Flashcard Study Sets
| What is a barium swallow test? | An imaging test using X-rays and barium contrast to visualize the pharynx and esophagus for structural and functional abnormalities. |
| What imaging technique is primarily used in a barium swallow? | Fluoroscopy, a real-time X-ray method showing organ movement. |
| What substance coats the upper GI tract in a barium swallow? | Barium sulfate, a radio-opaque contrast medium. |
| How does barium sulfate enhance X-ray imaging? | It absorbs X-rays, coating the pharynx and esophagus to highlight structure and motion. |
