MR enteroclysis: A nasojejunal tube is used for a special MRI procedure called enteroclysis. Putting the tube directly into the small bowel allows the radiologist to fill the intestine with contrast fluid very quickly and get a very good look at the intestine to see if there are polyps, masses, strictures or inflammatory wall thickening. Just drinking the fluid would never fill the intestine completely.
