摘　　要：目的 :探讨多层螺旋CT(MSCT)阴性法胰胆管造影 (N CTCP)对低位胆管梗阻性疾病的诊断价值。方法 :对 3 0例胆管结石、胆管癌、胰头癌、壶腹癌进行N CTCP成像 ,并与内窥镜逆行胰胆管造影 (ERCP)及手术病理结果对照。结果 :3 0例均一次屏气完成扫描 ,N CTCP成像显示胰胆管满意 ,MinIP对判断胆管梗阻和定位诊断准确率为10 0 %,定性诊断准确率为 78.5 %。结论 :N CTCP对低位胆管梗阻性疾病定位准确 ,对胆管结石及恶性胆管梗阻判断有较高准确性。结合轴面源像 (ASI)可提高对胆管细小结石的定性诊断。Objective:To evaluate the negative MSCT cholangiopancreatography (N CTCP) in diagnosis of lower bile duct obstruction.Methods:30 patients with choledocholithiasis,cholangiocarcinoma,pancreatic head carcinoma and ampullar tumor were examined by N CTCP.The results of N CTCP,ERCP and surgical pathology were analysed.Results:All patients were examined successfully to demonstrate bile and pancreatic ducts.The accuracy rate of the location and characterization of low obstruction of bile duct with MinIP was 100% and 78.5%,respectively.Conclusions:N CTCP can accurately define the obstructive site in lower bile duct obstructive diseases,and its specificity for the diagnosis of choledocholithiasis and malignant biliary obstruction is very high.N CTCP together with axial source image can improve the diagnosis of biliary mini stones.
