摘　　要：目的探讨胎儿生长受限胎盘与临床结局评估中MRI扩散加权成像的应用准确性研究。方法选取2017年1月至2019年12月确诊为胎儿生长受限的孕妇43例作为研究组,根据分型不同分为两组,研究1组19例(不匀称型)和研究2组24例(匀称型),选取同期产检显示为正常妊娠孕妇20例作为对照组,对所有孕妇的MRI图像回顾性阅片,比较三组孕妇基线资料、胎盘各项指标、出生时胎儿各项指标、并发症发生情况。结果所有孕妇妊娠在28~40周内,胎盘位于子宫后壁、前壁、侧壁,呈圆盘状,年龄、MRI筛查时孕周、出生孕周等基线资料具有可比性(P>0.05);三组的胎盘厚度无明显差异(P>0.05),研究1组与对照组的胎儿头围、胎儿身长无明显差异(P>0.05),研究1组与研究2组胎儿体重、胎儿5minApgar评分无明显差异(P>0.05),但研究2组的胎盘体积均低于对照组、研究1组(P<0.05);研究2组、研究1组的胎盘ADC值均低于对照组(P<0.05);研究2组胎儿头围、胎儿身长、胎儿体重、胎儿5minApgar评分均低于对照组,胎儿头围、胎儿身长、均低于研究1组(P<0.05);研究1组胎儿体重、胎儿5minApgar评分均低于对照组(P<0.05);研究2组、研究1组并发症均高于对照组(P<0.05)。结论在MRI成像中,不同分型胎儿生长受限胎盘特征存在一定差异,对不同分型胎儿生长受限胎盘结构和功能,MRI扩散加权成像能够从微观、宏观角度进行判断,从而进行精准的治疗,具有重要的临床意义。Objective To investigate the accuracy of MRI diffusion weighted imaging in the assessment of fetal growth restriction placenta and clinical outcomes.Methods Selection in January 2017-December 2019 pregnant women diagnosed with fetal growth restriction 43 cases as a team,according to different classification is divided into two groups,study 1 group 19 cases(asymmetrical type)and study 2 group 24 cases(fit),select the display of the same period of normal pregnancy pregnant women 20 cases as control group,MRI images were retrospectively read for all pregnant women,compared three groups of pregnant women the baseline data,placenta,born fetus the indicators,the indicators complications occurred.Results The placenta of all pregnant women was located in the posterior wall,anterior wall and lateral wall of the uterus within 28-40 weeks.The placenta was disc-shaped.The baseline data of age,gestational weeks and gestational weeks at the time of MRI screening were comparable(P>0.05).Three groups of placental thickness has no obvious difference(P>0.05),the study group and control group 1 fetal head circumference and fetal body length has no obvious difference(P>0.05),study 1 and study 2 group,fetal fetal weight 5 minapgar score no significant difference(P>0.05),but the placenta volume 2 group were lower than the control group,the study 1 group(P<0.05);The placental ADC values of the 2 and 1 groups were lower than those of the control group(P<0.05).Fetal head circumference,fetal body length,fetal body weight and fetal apgar score of 5 min.were all lower than the control group,and fetal head circumference and fetal body length were all lower than the control group(P<0.05).Fetal weight and apgar score of 5min in the first group were lower than those of the control group(P<0.05).Complications in the 2 and 1 groups were higher than those in the control group(P<0.05).Conclusion In MRI,there are some differences in placental characteristics of different types of fetus with growth restriction.For the placental structure and function
