目的:探讨胎盘植入介入治疗前后的MRI征象,评价MRI的诊断价值.方法:回顾性分析2009年1月至2012年4月间28例疑胎盘植入行介入治疗(子宫动脉栓塞术)的患者MRI资料,与手术和/或临床综合诊断标准相比较,分析胎盘植入介入治疗前后MRI征象.结果:胎盘植入的 MRI 表现:胎盘信号不均、胎盘下肌层变薄或消失、动态增强胎盘植入部分明显强化呈“花环状”或“结节状”.介入治疗后3个月及1年后复查MRI,显示增大子宫体积基本恢复正常大小,子宫肌层仍可见受侵异常信号改变,植入胎盘与宫壁融合.结论:MRI能显示胎盘植入部位及子宫肌层受侵程度,对胎盘植入介入治疗的疗效评价具有重要参考价值.

objective:To explore MRI signs and diagnostic value of MRI for placental adhesive disorders before and after interventional therapy. Methods: From Jan 2009 to Apr 2012, 28 patients with placental adhesive disorders treated by embolization received MRI examination and compared with the results of operation and/or clinical diagnosis. The MRI findings before and after interventional therapy were retrospectively analyzed. Results:On MRI images, the placenta demonstrates a heterogeneous signal, isointense to myometrium. the myometrium become quite thin and it can be difficult to visualize in patients with placenta percreta. On Gadolinium-enhanced T1WI, the placental tissue invaded the myometrium in the shape of “garland” or “nodul”. MRI features of all patients by interventional therapy after three or twelve months showed that the placental tissue was confluent with the uterine wall and the myometrium demonstrates a heterogeneous signal. Conclusion: MRI can display the placental implantation site and myometrial invasion degree of placenta implantation;it has an important reference value and can accurately evaluate curative effect before and after interventional therapy to placental adhesive disorders.
