Abstract
OBJECTIVE. The purpose of our report is to describe morphologic abnormalities of the small bowel in a population of patients with known celiac disease using MR imaging with polyethylene glycol solution as an oral contrast agent. CONCLUSION. Polyethylene glycol—enhanced MR imaging is a noninvasive (no ionizing radiation is used), feasible, and reproducible imaging technique in both adult and pediatric populations. Findings on polyethylene glycol—enhanced MR imaging, similar to those of conventional barium studies, may suggest a diagnosis of celiac disease because the technique can not only reveal intestinal involvement but also show extraintestinal findings.
