摘要
目的研究螺旋CT与MRI诊断胆总管结石价值。方法回顾性分析本院2012年6月至2013年4月经手术证实的40例胆总管结石患者的全部资料,并对这些患者的胆总管结石的CT和MRI检查结果进行分析。结果 CT的敏感度为33.1%,特异度为100%,假阳性率为0%,假阴性率为33.3%,准确度为73.5%,MRI的敏感度为96.6%,特异度为95.1%,假阳性率为3.3%,假阴性率为12.6%,准确度为96.6%,结果具有统计学意义(P<0.05)。结论 MRI对胆总管结石的诊断优于螺旋CT,在临床实践中有一定的指导意义。
Objective Researched spiral CT and MRI diagnosis of choledocholithiasis＇ value. Methods Retrospective analysed our hospital from June 2012 to April 2013, 40 cases of surgically confirmed choledocholithiasis patients＇ all the information, and analyzed these patients＇ choledocholithiasis＇ CT and MR/results. Results CT sensitivity was 33.1% and specificity was 100% and had 0% false positive rate. False negative rate was 33.3%, and accuracy was 73.5%, MRI had a sensitivity of 96.6% and a specificity of 95.1%, false positive rate was 3.3%, false negative rate was 12.6% and accuracy was 96.6%, the result was statistically significant （P〈0.05）. Conclusion MR/diagnosis of choledocholithiasis was better than spiral CT, in clinical practice had certain guiding significance.
