摘　　要：目的分析超声、磁共振成像(MRI)快速扫描序列对胎儿先天性肾脏异常诊断的应用价值。方法回顾性收集2017年1月至2019年4月在经常规产前检查怀疑为胎儿先天性肾脏异常的33例孕妇临床资料及影像学资料(超声、MRI检查),观察胎儿肾脏基本情况等,并以随访结果为准,比较不同检查对胎儿先天性肾脏异常检出符合率。结果33例孕妇中,胎儿先天性肾脏畸形31例,其中肾脏积水13例,肾脏发育不良(发育不完全、多房性肾囊变、多囊性肾发育不全)12例,肾脏异位4例,肾融合1例,肾脏重复畸形1例。MRI检查对胎儿先天性肾脏异常检出符合率为100.00%,超声检查90.32%,MRI检查符合率虽高于超声检查,但两者数据比较无差异(P>0.05)。结论超声、MRI快速扫描序列对胎儿先天性肾脏异常诊断中均有一定的使用价值,超声实用于产前筛查,MRI快速扫描序列不受胎儿体位、羊水等情况影响,对胎儿畸形方面诊断效果显著,无法明确诊断时可将MRI作为补充诊断。Objective To analyze the application value of ultrasound and magnetic resonance imaging(MRI)fast scanning sequences in the diagnosis of fetal congenital kidney abnormalities.Method The clinical data and imaging data(ultrasound,MRI)of 33 pregnant women suspected to be fetal congenital kidney abnormalities by routine prenatal examination from January 2017 to April 2019 were collected retrospectively.The situation such as basic conditions of the fetal kidney were observed,and the accuracy of different examinations in the detection of fetal congenital kidney abnormalities was compared based on the follow-up results.Results In the 33 pregnant women,there were 31 cases with fetal congenital kidney malformation,including 13 cases with hydronephrosis,12 cases with kidney dysplasia(ateliosis,multilocular renal cystic changes,and polycystic renal dysplasia),and 4 cases with ectopic kidney,1 case with renal fusion,and 1 case with renal double malformation.The accuracy of MRI examination in the detection of fetal congenital kidney abnormality was 100.00%,and accuracy of ultrasound examination was 90.32%.Although the accuracy of MRI examination was lower than that of ultrasound examination,there was no difference between them(P>0.05).Conclusion Ultrasound and MRI rapid scanning sequences have some value in the diagnosis of fetal congenital kidney abnormalities.Ultrasound is used for prenatal screening.MRI rapid scanning sequences are not affected by fetal position and amniotic fluid,etc.,and it has a significant effect in the diagnosis of fetal malformation.When the diagnosis was not clear,MRI can be used as a supplementary diagnosis.
