摘　　要：目的　探讨螺旋CT(SCT)胆管造影 (SCTC)三维成像在诊断胆管疾病中的价值及其真实性。方法　 2 6例疑胆系疾病患者行经内窥镜逆行胆管造影 (ERC)和SCT胆管造影后三维成像 ,将SCTC三维成像与ERC图像进行非双盲双照 ,13例经手术病理证实。结果　SCTC成功率 10 0 % ,三维成像与ERC图像相似 ,根据SCTC三维成像可对 92 .3 % ( 2 4/ 2 6例 )肝内外胆管病变做出与ERC或手术病理一致诊断 ,SCTC三维成像对ERC未成功、显示不完全病例提供可靠的补充诊断信息。其空间分辨率及对肝内细小胆管腔内结石显示逊于ERC。结论　SCTC三维成像是无创性检查技术 ,对肝外胆管疾病诊断和治疗方法选择具有指导作用 。Objective To evaluate the clinical value and reliability of three dimensional sprial CT cholangiography(SCTC).Methods Twenty-Six patients with suspected biliarytract diseases underwent intravenous SCTC and ERC,the images of ERC and 3D SCTC were retrospectively reviewed and analysied by nonblind method.The last diagnosis were comfirmed by operation and pathology in 13 cases.Results The rate of sucecess of intravenous chologiography with sprial CT cholangiography was 100%,the images of 3D SCTC were similar to these of ERC.The diagnosis made by relying on 3D SCTC images was coincident with ERC or operation and pathology.The available diagnositic informations could be obtained by 3D SCTC images in patients with unsuccessful on inadequate ERC.The spatial resolution and demenstration of intrahapatic biliary cholothiasis were alightly inferior to that of ERC.Conclusion 3D SCTC is a safe and available noninvasive imaging technique,it is of great reliable in the selection of diagnosis or therapeutics extrahepatic biliary tract diseases.It may be a substitute ERC for the demenstration of biliary tract diseases.
