摘　　要：目的:探讨磁共振胰胆管成像(MRCP)和CT扫描在胆道系统结石诊断中的临床应用效果。方法:回顾性收集本院2016年1月—2020年6月经临床证实为胆道系统结石患者50例,所有患者均行MRCP和CT扫描两种检查方法,通过卡方检验比较两种检查方法诊断胆道结石的准确率。结果:在50例胆道系统结石患者中,胆囊结石25例,肝内胆管结石5例,胆总管结石15例,多部位结石5例。MRCP检查确诊胆道结石45例,确诊率90.0%(45/50);CT扫描确诊胆道结石36例,确诊率72.0%(36/50);比较这两种检查方法的确诊率,具有统计学差异(P<0.01)。按胆道结石大小分为两组:在结石≥1.0cm患者23例中,MRCP检出22例,确诊率95.7%(22/23);CT检出21例,确诊率91.3%(21/23),两种检查方法的确诊率比较,无统计学差异(P>0.05)。在结石<1.0cm患者27例中,MRCP检出25例,确诊率92.6%(25/27);CT检出18例,确诊率66.7%(18/27),两种检查方法的确诊率比较,具有统计学差异(P<0.01)。结论:在胆道系统结石的检出方面,MRCP检查优于CT扫描,尤其是胆道结石<1.0cm的患者,应首选MRCP检查。Objective:To explore the clinical application effect of MRCP and CT scanning in the diagnosis of biliary system stones.Methods:Fifty patients with biliary tract stones confirmed by clinical practice from January 2016 to June 2020 were collected retrospectively.All patients underwent MRCP and CT scanning,and the accuracy of diagnosis of biliary tract stones was compared by Chi-square test.Results:Among 50 patients with bile duct stones,there were 25 gallstones and 15 common bile duct stones.45 cases of bile duct stones were diagnosed by MRCP,and the diagnosis rate was 90.0%(45/50).36 cases of biliary calculi were diagnosed by CT scan,and the diagnosis rate was 72.0%(36/50).Comparing the diagnostic rate of the two methods,there is a statistical difference(P<0.01).According to the size of bile duct stones,they were divided into two groups:among 23 patients with stones of≥1.0 cm,22 cases were detected by MRCP,and the diagnostic rate was 95.7%(22/23);21 cases were detected by CT,and the diagnosis rate was 91.3%(21/23).There was no significant difference between the two methods(P>0.05).Among 27 patients with stones less than 1.0 cm,MRCP detected 25 cases,with a definite diagnosis rate of 92.6%(25/27).18 cases were detected by CT,and the definite diagnosis rate was 66.7%(18/27).The definite diagnosis rate of the two methods was statistically different(P<0.01).Conclusion:MRCP is superior to CT scan in the detection of bile duct stones,especially for patients with bile duct stones less than 1.0 cm,MRCP should be the first choice.
