摘要
目的:胎盘植入是产科分娩的严重并发症,当超声诊断困难时MRI可以弥补其局限性,本研究分析了磁共振完全平衡的稳态(CBASS)序列的诊断价值。方法:采用CBASS序列对2015年1月至2016年12月东莞市大朗医院25例超声怀疑胎盘植入的孕妇进行检查,通过观察胎盘暗带、异常血管影、局部胎盘隆起、子宫肌层变薄、结合带信号中断及胎盘信号不均匀六个影像特征进行打分,从而绘制出受试者工作特征曲线(ROC)。结果:诊断效能分别为胎盘暗带(0.93;P=0.009)、异常血管影(0.91;P=0.007)、胎盘隆起(0.90;P=0.005)、结合带信号中断(0.89;P=0.003)、胎盘信号不均匀(0.86;P=0.002)。结论:CBASS序列是诊断胎盘植入的有效工具,可以结合多种影像特征对其进行准确诊断。
Objective Placenta accrete is a serious complication of obstetric delivery.When ultrasound is difficult to diagnose,MRI can make up for its limitations.This study explored the diagnostic value of magnetic resonance CBASS sequence.Methods The Placenta accrete pregnant women were examined by CBASS sequence.The placenta accrete was observed by observing dark band,abnormal vascular shadow,local placental uplift,myometrial thinning,combined with signal interruption and placental signal heterogeneity.The work characteristic curve of the subject is drawn.Results The diagnostic performance was placental dark band(0.93;P=0.009),abnormal vascular shadow(0.91;P=0.007),placental uplift(0.90;P=0.005),combined with signal interruption(0.89;P=0.003),placental signal is not heterogeneity(0.86;P=0.002).Conclusion CBASS sequence is an effective tool for the diagnosis of placenta accreta,which can be accurately diagnosed with relative imaging features.
