[背景]分析回盲部病变的小肠MRI造影检查表现.评价其在回盲部疾病鉴别诊断中的应用价值.[病例报告]回顾性分析16例胃肠道疾病的回盲部病变临床资料.并与小肠镜检查结果进行比较.行MRI造影检查前口服给予2.5%(质量分数)等渗甘露醇溶液,之后皮下注射给予山莨菪碱.扫描方法包括冠状面单次激发快速自旋回波序列(SSFSE)、冠状面T2WI脂肪抑制序列、冠状面T1WI脂肪抑制序列和横轴位弥散加权成像,后行带脂肪饱和技术的LAVA扫描序列增强扫描.观察小肠肠管形态、管腔扩张程度、管壁厚度、肠管周围脂肪间隙、小肠管壁的强化程度及肠系膜周围淋巴结肿大程度.结果见,16例患者均可接受等渗甘露醇溶液,均未发现并发症,其中包括Crohn病8例、炎性肠病(结核待排)5例、消化道出血2例、肠易激1例.[讨论]小肠MRI造影检查安全、无创、无电离辐射,可全方位多维显示肠道病变.
[Background] To analyze the small bowel MRI findings of ileocecal lesions and evaluate its value in the differential diagnosis of ileocecal diseases. [Case Report] The clinical data of 16 cases of ileocecal lesions of gastrointestinal diseases were retrospectively analyzed. And compared with the results of enteroscopy.One was given 2.5% (mass fraction) of isotonic mannitol solution before MRI angiography, then administered anisodamine subcutaneously.The scanning method included coronal single shot rapid spin echo ( SSFSE), coronal T2WI fat suppression sequence, coronal T1WI fat suppression sequence and horizontal axis diffusion weighted imaging, followed by LAVA scan sequence enhanced scanning with fat saturation technique.Observed intestinal morphology, lumen expansion, wall thickness , The fat gap around the intestine, the degree of enhancement of the small intestine wall, and the degree of lymphadenopathy around the mesentery.Results, 16 patients were able to accept isotonic mannitol solution, no complications were found, including Crohn’s disease in 8 cases, inflammatory Intestinal disease (TB to be discharged) in 5 cases, gastrointestinal bleeding in 2 cases, irritable bowel in 1 case. [Discussion] small bowel MRI imaging safety, noninvasive, non-ionizing radiation, comprehensive multi-dimensional display of the intestine Change.
