目的 比较MSCT及MRCP+MR在胆道 梗阻性病变中诊断价值。方法 选择我院 2013年1月-2015年8月收治66例胆管梗阻 患者进行研究，均行MSCT与MRCP联合MR检 查，观察2种方法影像学表现，以手术病 理检查结果为基准统计2种检查方法的定 位及定性诊断符合率并比较。结果 定位 诊断方面，CT总符合率为97.0%(64/66)， MRI为100.0%(66/66)，差异无统计学意 义(P＞0.05)；定性诊断方面，CT良性 病变诊断符合率为76.2%(32/42)，MRI 为88.1%(37/42)，差异无统计学意义(P ＞0.05)，CT恶性病变的诊断符合率为 75.8%(18/24)，低于MRI 95.8%(23/24)， 差异有统计学意义(P＜0.05）。结 论 MSCT及MRCP+MR在胆道梗阻性病变诊断中 的应用均有较好效果，而MRCP+MR对恶性 病变的诊断准确率更高，临床价值更大

Objective To compare the diagnostic value of MSCT and MRCP+MR in biliary obstructive lesions. Methods 66 patients with bile duct obstruction treated in our hospital from January 2013 to August 2015 were selected as the research objects. All patients underwent MSCT and MRCP combined with MR examination. Imaging findings of the two methods were observed. The results of surgical pathology were taken as the standard to statistically analyze and compare the coincidence rates of positioning and qualitative diagnosis of the two examination methods. Results In terms of positioning diagnosis, the total coincidence rate of CT was 97.0%(64/66) while of MRI was 100.0% (66/66)(P＞0.05); In terms of qualitative diagnosis, the coincidence rates of CT in the diagnosis of benign lesions was 76.2%(32/42) while of MRI was 88.1% (37/42)(P＞ 0.05). The coincidence rates of CT in the diagnosis of malignant lesions [75.8%(18/24)] was lower than that of MRI [95.8%(23/24)](P＜0.05). Conclusion Both of MSCT and MRCP+MR have good effects in the diagnosis of biliary obstructive lesions while MRCP+MR has higher diagnostic accuracy in the diagnosis of malignant lesions and higher clinical value.
