How has MDCT changed small bowel evaluation

How has MDCT changed small bowel evaluation? 

MDCT with coronal and sagittal MPRs can image the entire abdomen in a single breath-hold acquisition, facilitating small bowel evaluation. Ideal small bowel imaging requires intraluminal and intravenous (IV) contrast and bowel distention to best evaluate the mucosa, bowel wall, and surrounding structures, including adjacent fat. Neutral contrast agent use, such as dilute 0.1% barium sulfate mixed with sorbitol (VoLumen), allows better depiction of the bowel wall and mucosa compared to positive contrast agents such as meglumine diatrizoate (Gastrografin). If the intraluminal contrast is administered orally, the procedure is termed CT enterography, but if the intraluminal contrast is administered via a nasojejunal tube, the procedure is termed CT enteroclysis.
