What is Upper Gastrointestinal (GI) Tract Radiography?

• An x-ray (radiograph) is a noninvasive medical test that helps physicians diagnose and treat medical conditions.
• Upper gastrointestinal tract radiography, also called an upper GI, is an x-ray examination of the esophagus, stomach and first part of the small intestine (also known as the duodenum). Images are produced using a special form of x-ray called fluoroscopy and an orally ingested contrast material such as barium.
• When the upper GI tract is coated with barium, the radiologist is able to view and assess the anatomy and function of the esophagus, stomach and duodenum.
• Upper gastrointestinal tract radiography or upper GI uses a form of real-time x-ray called fluoroscopy and a barium-based contrast material to produce images of the esophagus, stomach and small intestine. It is safe, noninvasive, and may be used to help accurately diagnose pain, acid reflux, blood in the stool and other symptoms.

Why do I need Upper Gastrointestinal (GI) Tract Radiography?

An upper GI examination helps evaluate digestive function and can detect:
• ulcers
• tumors
• inflammation of the esophagus, stomach and duodenum
• hiatal hernias
• scarring
• blockages
• abnormalities of the muscular wall of GI tract• anatomical problems such as intestinal malrotation (a twisting of a babys intestine)
The procedure is also used to help diagnose the cause of symptoms such as:
• difficulty swallowing
• chest and abdominal pain
• reflux (a backward flow of partially digested food and digestive juices)
• unexplained vomiting
• severe indigestion
• blood in the stool (indicating internal GI bleeding)

Any preparation needed?

• You should inform your physician of any medications being taken and if there are any allergies, especially to iodinated contrast materials.
• Women should always inform their physician and x-ray technologist if there is any possibility that they are pregnant.
• To ensure the best possible image quality, your stomach must be empty of food.
• You will be asked to remove some of your clothes and to wear a gown during the exam.
• You may also be asked to remove jewelry, removable dental appliances, eye-glasses and any metal objects or clothing that might interfere with the x-ray images.
