Abstract： 目的评价口服大剂量2.5%等渗甘露醇多层螺旋CT小肠造影(multislice CT enterography,MSCTE)的可行性和临床价值. 方法 21例志愿者、91例疑有小肠病变患者每人口服约1500 ml 2.5% 等渗甘露醇后,静脉注入20 mg 山莨菪碱注射液,随后行多层螺旋CT三期扫描,并在Wizard工作站上进行多平面重建(multiplanar reformation,MPR)、最大密度投影(maximum intensity projection,MIP)和容积重建技术(volume rendering technique,VRT)重建.将正常组小肠分为十二指肠、空肠和回肠三部分,测量了各段小肠的管径和肠壁强化程度,并分别以 0、1、2、3 分表示适度充盈的肠段部分占所评估肠段的 30%以下, 30%～50%以下, 50%～80%以下和80%以上.分析不同小肠病变的MSCTE表现,并比较了其中24例小肠插管造影与MSCTE的诊断结果. 结果所有受试者均认为等渗甘露醇微甜,易接受,未发现并发症.十二指肠、空肠及回肠的充盈度分别为2.52、2.33和2.81分; MSCTE清楚地显示了肿瘤、Crohn病、粘连性肠梗阻等多种小肠疾患的肠内、肠壁、肠外血管、系膜及腹内脏器情况; MSCTE检查与临床诊断符合率为95.6%(87/91),而小肠插管造影的诊断符合率为87.5% (21/24).结论 MSCTE是1种简便、易行、经济实惠、能全方位、多维显示小肠疾病的方法.
