摘　　要：目的探讨磁共振成像(MRI)在凶险性前置胎盘诊断中的价值。方法回顾性分析2018年1月至2020年1月在我院就诊的120例凶险性前置胎盘患者的临床资料,其中合并胎盘植入患者79例,未合并胎盘植入患者41例,比较超声和MRI诊断结果。结果本组MRI诊断凶险性前置胎盘的准确率为93.33%,明显高于超声诊断的74.17%(P<0.05);其中孕周<37周和孕周≥37周患者的MRI诊断准确率分别为88.89%和96%,明显高于超声诊断的71.11%和76%(P均<0.05)。胎盘植入与无胎盘植入患者的年龄、孕周比较,差异均无统计学意义(P>0.05);在合并胎盘植入的79例患者中,MRI诊断准确率为94.94%,明显高于超声诊断的69.92%(P<0.05);在无胎盘植入的41例患者中,MRI和超声诊断准确率比较,差异无统计学意义(P>0.05)。结论MRI在凶险性前置胎盘诊断中有较好的价值,可有效鉴别胎盘植入型凶险性前置胎盘;临床需积极对有剖宫产史的再妊娠患者进行筛查,以尽早干预。Objective To explore the value of magnetic resonance imaging(MRI)in the diagnosis of pernicious placenta previa.Methods The clinical data of 120 cases diagnosed sinister placenta previa admitted from January 2018 to January 2020 were enrolled and analyzed retrospectively in our hospital,including 79 cases combined with placenta accreta and 41 cases without placenta accrete.All cases were diagnosed by MRI and ultrosonography.The outcomes of ultrasound and MRI were compared.Results The diagnostic accuracy of MRI was 93.33%for dangerous placenta previa,which was significantly higher than 74.17%of ultrasonography(P<0.05).The diagnostic accuracy of MRI was 88.89%in the patients with gestational weeks<37 and 96%in the patients with gestational weeks≥37,which were higher than ultrasound diagnostic accuracy of 71.11%and 76%respectively(P<0.05).There was no significant difference in age and gestational age between the patients with and without placenta implantation(P>0.05).In the patients combined with placenta implantation,the diagnostic accuracy of MRI was 94.94%,and which was obviously higher than 69.92%of ultrasound(P<0.05).No significant difference was found in the diagnostic accuracy between MRI and ultrasound in the patients without placental implantation(P>0.05).Conclusions MRI can identify pernicious placenta previa with accrete effectively and play an important role in the diagnosis of placenta previa.Actively screening and early intervention measures would be applied as possible as we can for the re-pregnancy patients with cesarean section history.
