摘　　要：目的:探讨低张饮水磁共振胰胆管造影(MRCP)结合不压脂T2WI及LAVA动态增强对十二指肠乳头腺癌的诊断价值。方法:收集资料齐全的28例十二指肠乳头腺癌患者,所有患者在常规MRCP、压脂T2WI基础上行低张饮水MRCP、不压脂轴位T2WI及LAVA动态增强扫描,比较低张饮水前后MRCP、不压脂和压脂T2WI对十二指肠乳头腺癌的显示效果,以及常规MRCP结合压脂T2WI及LAVA动态增强与低张饮水MRCP结合不压脂T2WI及LAVA动态增强对十二指肠乳头腺癌的诊断准确率。结果:28例患者中,75.0%(21/28)低张饮水后较低张饮水前肠管进一步充盈扩张,89.2%(25/28)低张饮水后胃肠蠕动较低张饮水前减弱,28.6%(8/28)低张饮水后较低张饮水前对病变梗阻部分的显示更准确,64.3%(18/28)不压脂T2WI序列对病变显示优于压脂T2WI序列,常规MRCP结合压脂T2WI及LAVA动态增强与低张饮水后MRCP结合不压脂T2WI及LAVA动态增强对十二指肠乳头腺癌的诊断准确率分别为82.1%(23/28)和92.8%(26/28)。结论:低张饮水MRCP结合不压脂T2WI及LAVA动态增强对十二指肠乳头腺癌具有较高的诊断价值。Objective:To investigate the diagnostic value of magnetic resonance cholangiopancreatography(MRCP)after oral hypotonic water combined with FRFSE T2WI and LAVA dynamic contrast enhanced scan for duodenal papillary adenocarcinoma.Method:A total of 28 patients with duodenal papillary adenocarcinomas confirmed by pathology were collected in the study.All patients underwent hypotonic MRCP,FRFSE T2WI and LAVA dynamic contrast enhanced scans on the basis of routine MRCP and FS T2WI.The display effect of duodenal papillary adenocarcinoma of routine MRCP and hypotonic MRCP,FRFES T2WI and FS T2WI,and the diagnostic accuracy of duodenal papillary adenocarcinoma with underwent routine MRCP,FS T2WI and LAVA contrast dynamic enhanced scans and hypotonic MRCP,FRFES T2WI and LAVA dynamic contrast enhanced scans were compared.Result:In all 28 patients,75.0%(21/28)of the patients had further filling and dilation of the intestines after hypotonic water;89.2%(25/28)hypotonic MRCP were more reduced than routine MRCP in bowel peristalsis;28.6%(8/28)hypotonic MRCP were more accurate than routine MRCP in displaying site of obstruction;64.3%(18/28)imagings of FRFES T2WI were better than FS T2WI;the diagnostic accuracy of duodenal papillary adenocarcinoma with underwent routine MRCP,FS T2WI and LAVA dynamic contrast enhanced scans and hypotonic MRCP,FRFES T2WI and LAVA dynamic contrast enhanced scans,were 82.1%(23/28)and 92.8%(26/28).Conclusion:MRCP after oral hypotonic water,FRFES T2WI and LAVA contrast dynamic enhanced scans is effectively valid in the diagnosis of duodenal papillary adenocarcinoma.
