【摘要】 目的:对比探讨磁共振胰胆管成像与B超诊断胆系结石的价值。方法:应用1.0T超导MRI扫描仪对171例胆系结石患者,胆囊结石68例,肝内胆管结石43例,胆总管结石60例,行B超检查及重T2加权多次激发FSE序列MRCP扫描。结果:B超及MRCP图像均能明确显示68例胆囊结石;103例胆管结石(43例肝内胆管结石和60例胆总管结石)在MRCP原始图像及MIP图像均可明确显示,而B超仅可显示其中的69例(67%)。结论:对于胆系结石的诊断,应有机地结合MRCP与B超检查,不能仅仅依靠某一种成像技术。胆囊结石首选B超检查,胆管结石应首选MRCP。更多还原

【Abstract】 Objective To evaluate the value of ultrasound(US)and MRCP in diagnosing biliary stones.Methods One hundred and seventy-one patients(gallbladder stones 68 cases,bile duct stones 43 cases and common bile duct stones 60 cases)had undergone ultrasound and MRCP with heavily T2 weighted fast spin echo sequences.Results Both US and MRCP could detect all of the 68 cases of gallbladder stones.All of the 103 cases of bile duct stones could be demonstrated on MIP images of MRCP sequences,whereas they had been detected only 69 cases(67%)on ultrasound examination.Conclusions MRCP and ultrasound examination is an organic whole of diagnosing biliary stones and could not rely on anyone kinds of technique.For gallbladder stones,we should prefer ultrasound examination,whereas for the bile duct stones,we should choose MRCP.更多还原
