Gastrointestinal Examinations

Gastrointestinal (GI) X-ray exams involve the use of barium enemas (with or without air), barium solutions, scope instruments and -ray machines. These products and instruments are used to diagnose problems throughout the digestive tract such as swallowing problems, abdominal pain, unexplained weight loss or bleeding, reflux, vomiting, hernias, intestinal tumors, polyps, inflammation of the intestines, and rectal-related problems.  
 The upper GI test examines the esophagus, stomach, and part of the small intestine.
 The lower GI test examines the large intestine and the rectum. For this test, barium is delivered into the rectum by enema.
