OBJECTIVE
To compare the diagnostic value study the technique of ultrasonography, magnetic resonance cholangiopancreatography (MRCP) and endoscopic retrograde cholangiopancreatography (ERCP) in common duct stones.
METHODS
Three hundreds and eighty-four patients suspected common duct stones from August 2005 to October 2007 were undergone abdominal ultrasonography, MRCP and ERCP.
RESULTS
There was stone in common duct in 370 and no stones in 14 of 384 patients. Ultrasonography indicated stones 268 cases, 8 false positive result was among them. MRCP diagnosed stones in 362 cases and false positive result in 6 cases, ERCP diagnosed stones 370 cases. The diagnostic accuracy of ultrasonography, MRCP and ERCP was 70.3% (260/370), 96.2% (356/370) and 100% respectively.
CONCLUSIONS
The diagnostic accuracy of ultrasonography for common duct stone was little higher, US should be used as a primary checking method. There was higher concordance between MRCP and ERCP for common duct stone. Combination of MRCP and ERCP can improve diagnostic accuracy of common duct stone.
目的
比较超声检查、磁共振胰胆管造影（MRCP）及内镜逆行胰胆管造影（ERCP）技术对胆总管结石的诊断价值。
方法
对2005年8月至2007年10月怀疑有胆总管结石的384例患者进行腹部超声检查、MRCP及ERCP检查。
结果
384例患者中370例胆总管有结石，14例无结石。超声检查提示结石268例，其中有8例假阳性结果。MRCP诊断结石362例，假阳性结果6例，ERCP诊断结石370例。超声检查、MRCP及ERCP的诊断准确率分别为70.3%（260/370）、96.2%（356/370）和100%。
结论
超声对胆总管结石的诊断准确率稍低，应作为初步检查方法。MRCP与ERCP对胆总管结石的诊断有较高的一致性。MRCP与ERCP联合应用可提高胆总管结石的诊断准确率。
