[Abstract] Objective: To discuss the MR features of the small intestinal disease of children, and to assess the usefulness of MR enterography (MRE) in pediatric patients.Materials and Methods: The MRI findings of l2 cases of small intestinal diseases proved by operation and pathology were reviewed. Before the examination, the children suspected of various kinds of small intestinal diseases were administered isosmotic mannnitol (2.5%) as oral enteric contrast agent and 0.3 mg/kg of raceanisodamine hydrochloride was injected intravenously, MR scanning was performed 5 to 10 minutes later. The pulse sequences include coronal true fast imaging with steady-state precession (TrueFisp) images, axial and coronal T1-weighted images, T2-weighted fat-suppressed images, coronal fat-suppressed three-dimensional gradientecho MR image, immediately followed by contrast enhanced axial and coronal T1-weighted fat-suppressed images.Results: The taste of isosmotic mannitol was good (slight sweet) and acceptable by all children. MRE features of many kinds of small bowel diseases were clearly displayed, including wall thickening, mesenteric fibrofatty change, mesenteric vasculature change, and so on. Six of 12 patients were Crohn’s disease, MRI displayed 16-segment inflammatory bowel which demonstrated wall thickening, luminal stenosis and enhanced image demonstrated intestinal lesion is significantly enhancement. Lymphoma, enteric persimmon lithiasis, intussusception, Chronic duodenal ulcer, duodenal perforation, gastrointestinal anastomotic ulcer one each.Conclusion: MRE is a simple, safety, noninvasive, efective method without the need for ionizing radiation for evaluating small bowel diseases.
