目的：评价三维螺旋ＣＴ胆道造影的诊断价值。方法：在静脉输入胆道造影剂Ｂｉｌｉｓｃｏｐｉｎ后，４２个病人进行了上腹部螺旋ＣＴ扫描，利用三维重建技术对胆道系统正常、正常变异及部分病变进行分析研究，并将其结果与两天之内进行的ＥＲＣＰ进行比较。结果：三维螺旋ＣＴ胆道造影准确地诊断胆道系统所有的正常、正常变异及所有的胆道梗阻、胆道结石，但在胆道结石的定量诊断方面有２（２／６）个病人的结石数量被低估；一个病人三维螺旋ＣＴ胆道造影仅诊断出胆总管结石而未能诊断出胆囊癌，但轴位图象可以清楚地显示出胆囊癌。模拟内窥镜方式可以更加直观地显示病变。结论：三维螺旋ＣＴ胆道造影可以作为一种准确而无创性的胆道系统检查方法。
Objective: To evaluate the diagnostic value of three-dimensional spiral CT cholangiography. Methods: Forty-two patients underwent spiral CT scans of the bile duct after intravenous infusion of Biliscopin. The normal and normal biliary tract was analyzed by three-dimensional reconstruction and the results were compared with those of two days The ERCP is compared. Results: Three - dimensional spiral CT cholangiography accurately diagnosed all normal and normal biliary tract obstructions and all biliary obstruction and biliary calculus, but the number of stones in 2 (2/6) patients was underestimated in the quantitative diagnosis of biliary stones. A patient with three-dimensional spiral CT cholangiography only diagnosed common bile duct stones and failed to diagnose gallbladder cancer, but axial images clearly show gallbladder cancer. Analog endoscopy can display lesions more intuitively. Conclusion: Three-dimensional spiral CT cholangiography can be used as an accurate and noninvasive method of biliary system examination.
