What Is An Upper GI Series?
A upper gastrointestinal (GI) series is a group of specialized X-rays that produce high quality images of the upper GI tract. The upper GI tract includes a noninvasive examination of the esophagus, stomach, and duodenum. A upper GI study often utilizes special tools such as a fluoroscopy, a special type of X-ray device, and barium swallow, a type of fluid taken orally to help outline specific areas of the upper GI tract. Some abnormalities are hard to detect by conducting a general X-ray. That is where fluoroscopies and barium come into play. If further studies are required, an upper GI series may include further barium studies or an endoscopy. An endoscopy is performed by a gastroenterologist with the goal of gathering more information after diagnostic imaging studies are completed.
