Fig. 3A —Optimal appearance of small bowel on CT enterography.
Constant homogeneity, wall conspicuity, and demarcation of bowel content from
surrounding tissues were optimal in image of distal ileal segment in
39-year-old man with abdominal pain (A) and good in image of jejunum
(B) in 44-year-old woman with right lower-quadrant pain.
