[目的]评价16层计算机断层摄影结合多平面重建技术在胆管阻塞病人中的应用。[方法]使用16层计算机断层摄影结合多平面重建技术(MPR)对60例被认为患有胆管阻塞的病人进行诊断。诊断中没有使用任何胆管造影剂。其中24例病人接受了磁共振胰胆管造影成像(MRCP)检查,16例病人进行了逆行胰胆管造影(ERCP)检查,28例病人进行了活组织切片检查或外科手术。我们将16层计算机断层摄影检查结果与磁共振胰胆管造影成像、逆行胰胆管造影、活组织切片检查及外科手术的结果进行了对比。以手术病理结果为标准。[结果]检查结果如下:胆总管结石(34例),恶性狭窄(14例),良性狭窄(2例),胆石症(12例)。1例病人的一枚小胆总管结石16层计算机断层摄影未能检出。2例16层计算机断层摄影初诊为胆管结石的病人在接受其他相关检查时诊断为恶性胆管狭窄。16层计算机断层摄影诊断胆管结石的准确率为91.1%。16层计算机断层摄影诊断胆管狭窄的准确率为87.5%。[结论]16层计算机断层摄影及多平面重建技术是一种快速和无创技术,在诊断胆管阻塞原因方面具有相当高的准确性。
[Objective] To evaluate the application of 16-slice computed tomography combined with multiplanar reconstruction in patients with biliary obstruction. [Methods] Sixty patients diagnosed as having obstruction of the bile duct were diagnosed using 16-slice computed tomography combined with multiplanar reconstruction (MPR). No biliary contrast agent was used in the diagnosis. Twenty-four of the patients underwent magnetic resonance cholangiopancreatography (MRCP), 16 underwent ERCP, and 28 underwent biopsy or surgical procedures. We compared 16-slice computed tomography findings with magnetic resonance cholangiopancreatography, retrograde cholangiopancreatography, biopsy and surgical procedures. The results of surgical pathology as the standard. [Results] The examination results were as follows: common bile duct stone (34 cases), malignant stenosis (14 cases), benign stenosis (2 cases) and cholelithiasis (12 cases). One patient had a small common bile duct calculi 16-slice computed tomography failed to detect. Two patients with newly diagnosed bile duct calculi in 16-slice computed tomography were diagnosed as malignant biliary strictures when receiving other related tests. The accuracy of 16-slice computed tomography in the diagnosis of bile duct stones was 91.1%. The accuracy of 16-slice computed tomography in the diagnosis of biliary stricture was 87.5%. [Conclusion] The 16-slice computed tomography and multiplanar reconstruction technique is a rapid and noninvasive technique with high accuracy in diagnosing the causes of cholangiocclusion.
