Upper gastrointestinal series is the radiographic examination of upper gastrointestinal tract. Esophagus, stomach and then duodenum are visible on the X-ray film by the use of the liquid suspension which may be barium or water-soluble contrast.
Fluoroscopy is used during upper GI series. A continuous beam of X-ray rays is passed through body part and is transmitted to the monitor so that body part and the motion of it can be seen in every detail. <u>In upper GI series, the fluoroscopy allows radiologist to see movement of barium through esophagus, stomach, and duodenum as the person drinks.</u>
