A Pattern Approach to the Abnormal Small Bowel: Observations at MDCT and CT Enterography

OBJECTIVE. Imaging of the vast array of pathologic processes occurring in the small bowel has been facilitated by recent advances, including the use of MDCT scanners that acquire isotropic data and neutral oral contrast agents that improve small-bowel distention.CONCLUSION. This review shows how a systematic pattern approach can be used to narrow the differential diagnosis when an abnormal small-bowel loop is detected on MDCT.
