摘要目的旨在探讨不使用静脉注射对比剂的MR DWI评估小肠克罗恩病炎性反应的效果不劣于常规对比增强(CE)MR小肠成像。材料与方法本前瞻性研究得到了机构审查委员会的批准和知情同意。50例疑似克罗恩病成人进行临床评估、MR小肠成像检查,并在1周内行回结肠镜检查。MR小肠成像包括常规成像和DWI(b=900 s/mm2)。在
Abstract Objective To investigate the effect of MR DWI in evaluating small bowel Crohn’s disease inflammatory response without intravenous contrast agent is not inferior to conventional contrast enhanced (CE) MR small bowel imaging. Materials and Methods The prospective study was approved and informed by the institutional review board. Fifty patients with suspected Crohn’s disease underwent clinical assessment, MR small bowel imaging, and colonoscopy at 1 week. MR small bowel imaging includes conventional imaging and DWI (b = 900 s / mm2). in
