摘　　要：目的探讨16层螺旋CT及其多平面重组技术(MPR)对胆总管下段梗阻病变的临床应用价值。方法38例胆总管梗阻的病例均采用16层螺旋CT进行扫描,在工作站上进行MPR影像后处理,并对结果进行比较和综合分析。结果38例病例中,胆总管中下段结石21例,胆总管癌8例,壶腹癌6例,胆管炎3例。16层螺旋CT及其多平面重组技术观察病变的大小范围、形态、密度等改变,对病变显示满意。结论多层螺旋CT重建能提供病变非常有价值的空间关系信息,对胆总管中下段梗阻定位准确,定性率较高;临床应用价值大,有利于临床医师选择治疗方案,制订手术计划。Objective To evaluate the value of 16-slice spiral CT（16-slice SCT） with its MRP in the diagnosis of obstruction of lower segment of the common bile duct. Methods Thirty-eight patients with obstruction of middle-lower segment of the common bile duct underwent 16-slice SCT. Images obtained with postprocessing techniques in MPR performed on a workstation for each case were reviewed. Results Among 38 cases, 21 were found stone in the middle-lower segment of the common bile duct;8 were of cancer of the common bile duct; 6 were of carcinoma of ampulla;3 were of cholangitis. The 16-slice SCT with MPR correctly demonstrated details and density,shape and size of lesions. Conclusion Sixteen-slice SCT with MPR techniques could provide valuable spatial information of obstruction of lower segment of the common bile duct which correlated well with that of pathological anatomy.
