摘要：

目的 探讨MRCP 及原始薄层图像联合T2WI-SPAIR 序列对胆总管结石的诊断价值。方法 回顾性分析59例经ERCP手术证实为胆总管结石患者术前的B超及MRI资料，比较B超、MRCP联合原始薄层图像、MRCP及原始薄层图像联合 T2WI-SPAIR序列对胆总管结石的诊断符合率，并进行统计学分析。结果 B超、MRCP联合原始薄层图像、MRCP及原始薄层图像联合T2WI-SPAIR序列对胆总管结石的诊断符合率分别为32.2%、88.14%和93.22%，三者比较,差异有统计学意义（P<0.05）。结论 MRCP及原始薄层图像联合T2WI-SPAIR 序列对胆总管结石的诊断准确率较高，临床应用价值显著。

ABSTRACT: Objective To investigate the clinical diagnostic value of MRCP and original slice images combined with T2WI-SPAIR sequence in choledocholithiasis. Methods A retrospective analysis of MRI data and B-scan materials of 59 cases of choledocholithiasis confirmed by ERCP surgery was carried out, the diagnostic accuracy of type -B ultrasound, MRCP combined with original thin slice images, MRCP and original thin slice images combined with T2WI -SPAIR sequence in common bile duct stone was compared and statistical analysis. Results The diagnostic accuracy of type -B ultrasound, MRCP combined with original thin slice images, MRCP and original thin slice images combined with T2WI-SPAIR sequence for common bile duct stones was 32.2%, 88.14% and 93.22% respectively, and the differences among the three methods were statistical significance (P<0.05). Conclusion MRCP and original slice images combined with T2WI-SPAIR sequence have higher accuracy in diagnosis of choledocholithiasis, and have significant clinical value.

KEYWORDS: MRCP; original slice images; T2WI-SPAIR sequence; bile duct stone; diagnosis
