CTE provides enough distention of the bowel not present during normal CT imaging to increase the ability to examine in lumen and internal lining of the small intestines. When the small bowel is not properly distended it can be difficult to see if there is a problem in that area. CTE also provides

due to its increased spatial resolution and better ability to examine the wall of the small intestine than traditional CT studies of the abdomen and pelvis. Findings on CTE that indicate active inflammation in the small bowel, possibly caused by Crohn's disease, include:
237:. The neutral agents are vitally important for the effective visualization of the lining of the small intestine. Use of positive contrast agents could make it difficult to see any inflammation in the lining. Neutral agents include water, EG electrolyte solution, 233:(Reglan) will be administered to assist with emptying the stomach and increase movement through the small intestines. Large amounts of an oral contrast agent are given to the patient. Neutral contrast agents are preferred over positive contrast agents such as 129:, many of the findings on Crohn's disease found on CTE can be caused by a wide variety of other conditions. Spasm and collapse of the small intestine, which can happen in Crohn's disease, can obscure imaging of that portion of the bowel even with CTE. 723:
