【摘要】：目的:探讨晚孕期各型胎盘植入MRI征象及其诊断价值。方法:回顾性分析2010年7月-2013年12月期间经手术及病理证实27例胎盘植入孕妇的临床资料。所有孕妇均行MRI检查。结果:粘连型3例,植入型15例,穿透型9例,均为前置胎盘。三型胎盘厚度及胎盘内流空血管数目分别为4.87cm/5.0;5.31cm/5.7;6.51cm/6.8。3例粘连型2例胎盘附着面呈弧形,1例呈结节状膨出,肌层连续;15例植入型11例胎盘结节状膨出,11例肌层渐进性消失,10例肌层异常信号;9例穿透型4例胎盘结节状膨出,5例块状突出,超过肌层轮廓,2例肌层渐进性消失,7例肌层中断,肌层信号均见异常,4例膀胱肌层信号异常。结论:常规MRI序列对胎盘植入的诊断与分型具有较高的应用价值,部分病例存在征象重叠。
[Abstract]:Objective: to investigate the MRI signs of placenta accreta in late pregnancy and its diagnostic value.Methods: the clinical data of 27 pregnant women with placenta accreta confirmed by operation and pathology from July 2010 to December 2013 were analyzed retrospectively.All pregnant women underwent MRI examination.Results: there were 3 cases of adhesive type, 15 cases of implantation type and 9 cases of penetrating type, all of them were placenta previa.The thickness of placenta III and the number of empty blood vessels in placenta were 4.87 cm / 5.0 ~ 5.31 cm / 5.7 ~ 6.51 cm / 6.8.3 cases of adherent type, 2 cases of placental adhesion were arcuate and 1 case was nodular bulge.15 consecutive cases of myometrium accreta 11 cases of placental nodular bulge 11 cases of progressive disappearance of myometrium 10 cases of abnormal signal of myometrium 9 cases of penetrating type 4 cases of placental nodular bulge 5 cases of bulge.There were 2 cases of progressive disappearance of myometrium and 7 cases of discontinuity of myometrium, and 4 cases of abnormal signal of bladder myometrium were found in all cases.Conclusion: routine MRI sequence is of great value in the diagnosis and classification of placenta accreta, and some cases have overlapping signs.
