摘　　要：目的探讨64层螺旋CT阴性法胰胆管成像(N-CTCP)对胆道梗阻部位、性质以及受累范围的诊断价值。方法 52例临床诊断为梗阻性黄疸的患者行64层螺旋CT中上腹部平扫和增强扫描,进行多平面重建(MPR)、曲面重建(CPR)及最小密度投影(MinIP),作出CT诊断并与手术及病理结果进行比较,评估该技术在诊断胆道梗阻部位、性质以及受累范围的诊断价值。结果N-CTCP及重建图像质量优良,对梗阻部位、梗阻性质和胆管壁及周围器官结构受累情况的诊断准确率分别为的100%(52/52)、96.2%(50/52)和100%(52/52)。结论 64层螺旋CT阴性法胰胆管成像是一种有效的检查方法,具有强大的图像后处理功能,对胆道梗阻部位、性质及胆管壁与周围器官结构受累情况的诊断准确率高,具有很好的临床应用价值。Objective To explore diagnostic value of 64-slice spiral CT negative cholangiopancreatography（N-CTCP） for obstructive location,cause and range of biliary tract.Methods 52 patients with obstructive jaundice proved by clinic or lab testing underwent 64-slice spiral CT pre-contrast and contrast scanning of abdomen,then the source images were post-processed by using MPR,CPR and Min IP.Diagnosis upon CT were compared with the results of surgery and pathology so as to assess the diagnostic value of N-CTCP for obstructive location,cause and range of biliary tract.Results Both N-CTCP and its reconstruction can provide high quality images.The diagnostic accuracy of N-CTCP for obstructive location,cause and affected biliary tract wall as well as abutting structures were 100%（52/52）,96.2%（50/52） and 100%（52/52）,respectively.Conclusion N-CTCP is an efficient method with powerful post-processing function.It has high clinical value due to the high diagnostic accuracy for obstructive location,cause and affected biliary tract wall as well as the abutting structures.
