摘要 目的:评价口服大剂量2.5%等渗甘露醇多层螺旋CT小肠造影的临床价值。材料和方法:36例患者口服1500ml 2.5%等渗甘露醇后,静脉注入20mg山莨菪碱注射液30-40min后行多层螺旋CT三期扫描,并进行多平面重建(MPR)、最大密度投影(MIP)和容积重建技术(VRT)重建。将小肠分为六组,分析小肠充盈情况。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。比较三种造影方法,其中以第三种效果最好。充盈良好率达88.5%,MSCTE清楚显示小肠肿瘤10例、肠粘连、肠系膜上动脉压迫综合征、肠梗阻等各1例,显示小肠疾患的肠内、肠壁、肠外及腹腔内脏器情况,显示胃、结肠癌共6例。结论:MSCTE是一种简便易行、经济实惠、能全方位多维显示小肠疾病的方法。
