MRCP综合检查技术诊断胆总管结石与其他影像学对比研究

A comparative study of MRCP combined with MRI diagnosis of choledocholithiasis and other related imagings

目的评价磁共振胰胆管成像(MRCP)综合检查技术诊断胆总管结石的价值。方法搜集胆总管结石患者56例,调取其磁共振、CT及B超检查报告及图片,统计三者检出率,利用卡方检验统计分析差异性;统计三者检出、未检出结石直径数据,综合比较三种检查方法的优劣并分析原因。结果 MRCP综合组,CT组,B超组诊断胆总管结石检出率分别为98.2%、77.1%、46.5%,卡方检验显示三者检出率差异有统计学意义。MRCP综合组、CT组及B超组检出结石直径分别为(1.17±0.68)、(1.37±0.60)、(1.38±0.63)cm,方差分析显示三者差异没有统计学意义。结论 MRCP综合检查技术诊断胆总管结石检出率显著优于B超及CT,但检出小结石能力三者无差异性。

Objective To evaluate the value of MRCP combined with MRI comprehensive diagnosis of choledocholithiasis.Methods We collected the MR,CT and ultrasound reports and imagings of 56 patients with choledocholithiasis,and figured out the respective de-tection rates with MR,CT and ultrasonography and analyzed their differences by using Chi-square test.Besides,the data of the stone di-ameters detected and undetected by MR,CT and ultrasonography were summarized and advantages as well as disadvantages of the three test methods were analyzed.Results The detection rates of MRCP combined with MRI diagnosis of choledocholithiasis,CT and ul-trosonography were 98.2%,77.1%,and 46.5%,respectively.By comparing three sets of data,the results of Chi-square test detection showed that the difference in detection rate was statistically significant.The stone diameters detected by MRCP combined with MRI,CT and ultrasonography were （1.17 ±0.68）,（1.37 ±0.60） cm,and （1.38 ±0.63） cm,respectively.Variance analysis results showed that there was no significant difference.Conclusions The detection rate of MRCP combined with MRI diagnosis of choledocholithiasis is significantly higher than that of ultrasonography and CT detection.But there is no difference in the ability to detect microlith.
