Adequacy of Bowel Wall Distension in Patients Undergoing CT Enterography: A Radiologist's Perspective

The evaluation of patients with suspected small bowel disease, particularly in inflammatory bowel disease (IBD), has always been challenging because of the small bowel length and location. Capsule endoscopy has the advantage of direct visualization of the bowel lumen, but it is relatively contraindicated in the presence of strictures and has limited ability to assess extraluminal abnormality [1]. CT enteroclysis, another modality of small bowel imaging, requires fluoroscopic placement of a naso-jejunal tube to infuse contrast material; therefore, it has the disadvantages of poor patient tolerance associated with nasojejunal tube insertion and additional radiation exposure during the examination [2, 3].
