摘　　要：目的:分析3.0T MRI的LAVA-Flex结合MRCP在诊断胆系结石的应用价值。方法:收集胆系结石患者254例,采用合MRCP检查及3.0T MRI的LAVA-Flex序列结合MRCP检查对患者进行诊断,分析LAVA-Flex结合MRCP在诊断胆系结石的应用价值。结果:LAVA-Flex联合MRCP序列检测254例患者中,20例胆囊合并胆总管结石病,30例肝内胆管结石,40例肝内胆管合并胆总管结石,72例胆总管结石,92例胆囊结石;采用LAVA-Flex联合MRCP序列阳性检出率高于单独MRCP序列扫描检查结果,且差异有统计学意义(P<0.05)。结论:采用3.0T MRI的LAVA-Flex序列结合MRCP检查对胆系结石进行评价时,可有效获取高信噪比的影像学图像,提高结石病灶的检出率,具有较高的临床应用价值。Objective:Analysis of 3 T MRI LAVA-Flex combined with MRCP in the diagnosis of bile duct stones.Methods:A retrospective analysis of 254 cases of biliary calculi in patients with clinical data,using LAVA-Flex sequence MRCP 3.0T MRI examination and diagnosis of patients with MRCP examination,analysis of LAVA-Flex combined with MRCP in the diagnosis of biliary calculi.Results:3T MRI LAVA-Flex combined with MRCP sequencing in 254 patients,20 cases of cholecystolithiasis combined with choledocholithiasis,30 cases of intrahepatic bile duct stones,40 cases of intrahepatic bile duct and common bile duct stones,72 cases of common bile duct stones,92 cases of gallbladder calculi;combined with LAVA-Flex sequence of MRCP positive rate was higher than that of single MRCP sequence scan results,and the difference between the statistical significance(P<0.05).Conclusions:3.0T MRI LAVA-Flex sequence combined with MRCP examination for the evaluation of biliary stones,can effectively obtain high signal-to-noise ratio imaging image,improve the detection rate of stone lesions,with high clinical value of LAVA-Flex.
