Upper GI study (1 of 2)  
 

This test involves the oral ingestion of barium, a radio-opaque substance, in order to image the upper digestive tract. It is important to remember that the study highlights intraluminal anatomy (the intestinal wall is not directly visualized, only the interface between barium in the lumen and the intestinal wall).
