To evaluate accuracy of multidetector computed tomography (MDCT) cholangiography in evaluation of cause of biliary tract obstruction.
MDCT cholangiographs of 50 patients with clinically suspected biliary tract obstruction were retrospectively reconstructed and reviewed. The causes of obstruction identified by MDCT were divided into three groups including calculus, benign stricture, and malignancy. Final diagnosis was based on pathological diagnosis or endoscopic retrograde cholangiopancreatography or follow-up. The MDCT diagnosis and final diagnosis were compared
The sensitivity, specificity, positive predictive value, and negative redictive value of MDCT cholangiography for detection of calculus, benign stricture, and malignancy were 91.7-100%, except for sensitivity and positive predictive value for detection of benign stricture, which were 66.7% and 66.7% respectively.
MDCT cholangiography is a fast, noninvasive technique that offers high diagnostic accuracy in evaluation of cause of biliary tract obstruction.
评估多排螺旋计算机断层扫描（MDCT）胆管造影在评估胆道梗阻原因方面的准确性。
对50例临床怀疑胆道梗阻患者的MDCT胆管造影进行回顾性重建和分析。MDCT确定的梗阻原因分为三组，包括结石、良性狭窄和恶性肿瘤。最终诊断基于病理诊断、内镜逆行胰胆管造影或随访结果。比较MDCT诊断结果与最终诊断结果。
MDCT胆管造影检测结石、良性狭窄和恶性肿瘤的敏感度、特异度、阳性预测值和阴性预测值分别为91.7% - 100%，不过检测良性狭窄的敏感度和阳性预测值分别为66.7%和66.7%。
MDCT胆管造影是一种快速、无创的技术，在评估胆道梗阻原因方面具有较高的诊断准确性。
