    【摘 要】目的：探讨胎盘植入的超声图像特征及诊断价值，分析漏诊原因，以提高胎盘植入的产前超声诊断率。方法：对 30 例产后确诊为胎盘植入的声像图进行回顾性分析。结果：1、产前彩色多普勒超声对前壁肌层胎盘植入的诊断率及检出率明显高于非前壁肌层胎盘植入。2、胎盘与子宫肌层界限欠清晰在胎盘植入的表现(胎盘增厚、胎盘与子宫肌层界限不清晰以及胎盘实质内腔隙性血流情况)中占主要部分。3、中央型前置胎盘的胎盘植入在前置胎盘中的检出率较高。结论：胎盘植入的超声声像图特征复杂多样，仍需进一步提高临床的诊断率及检出率； 前壁肌层的胎盘植入以及中央型前置胎盘有利于超声的诊断及检出。

    【Abstract】Objective：To investigate the ultrasonographic features and diagnostic value of placenta implantation， and to analyze the causes of missed diagnosis， so as to improve the prenatal ultrasonographic diagnostic rate of placenta implantation..Methods： the sonographic findings of 30 cases of postpartum placenta accreta were retrospectively analyzed. Results： The diagnosis rate and detection rate of placenta implantation in anterior muscle layer by prenatal color Doppler ultrasound were significantly higher than that of non-anterior muscle layer placenta implantation. 2 ......
