An Upper GI (gastrointestinal) x-ray is a tool used to examine the pharynx, esophagus, stomach and first part of the small intestine. The exam uses a special form of x-ray called fluoroscopy and a contrast material.

Specifically, a GI examination helps evaluate digestive function and detection of ulcers, tumors, inflammation, hiatal hernias, blockages, and abnormalities of the muscular wall of gastrointestinal tissues.

The procedure is also useful in diagnosing problems associated with difficulty in swallowing, pain, reflux, unexplained vomiting, severe indigestion, or blood in the stool (indicating internal GI bleeding).

This examination is generally performed on an outpatient basis and is often scheduled in the morning to reduce the amount of time a patient has to fast.

Procedure

During the exam, an Inland Imaging radiologist or midlevel (PA or ARNP) and technologist will guide the patient through the upper GI series.

The patient will be asked to swallow a special barium drink that the radiologist or midlevel will watch pass through the digestive tract using fluoroscopy, a technology that produces moving images which are viewed on a monitor.

The patietnt will be positioned at different angles to help move the barium through different parts of your body. After the upper gastrointestinal tract is adequately coated with the barium, x-ray images will be taken and stored for further review.

Then, the patient will be asked to remain still for a few seconds while the x-ray picture is taken. An x-ray technician will activate the x-ray machine and record the image. The exam is usually completed within 20 minutes to 30 minutes.
