探讨前置胎盘并胎盘植入的MRI诊断价值

Explore the MRI Diagnosis of Placenta Previa and Placenta Increta

目的:探讨前置胎盘并胎盘植入的MRI诊断价值。方法:选择2017年6月~2019年6月经手术证实前置胎盘患者66例进行回顾性分析,合并前置胎盘并植入患者50例,总结比较不同序列对前置胎盘并植入的评价。结果:HASTE序列子宫肌层、联合带、胎盘内低信号、植入灶情况显示率高于true FISP序列(P<0.05),血管情况显示率差异无统计学意义(P>0.05);前置胎盘伴植入盘内信号不均、胎盘内增粗血管影、T_(2)W1胎盘内条带状低信号影、胎盘与子宫分界不清影像特征高于前置胎盘不伴植入的患者(P<0.05),前置胎盘伴植入子宫轮廓局部外凸、膀胱突起影像特征低于前置胎盘不伴植入的患者(P<0.05)。结论:MRI能提高前置胎盘并胎盘植入诊断效能,对临床上制定合理的治疗方案具有重大意义。

Objective:To study the MRI diagnostic value of placenta previa and placenta increta.Methods:In June 2017~June 2019 after surgery confirmed 66 patients with placenta previa were retrospectively analyzed,50 patients with implanted placenta previa and merger,summary to compare different sequence for evaluation of placenta previa and implanted.Results:HASTE sequence in the myometrium,joint belt,placenta low signal,implanted focal display rate is higher than true FISP sequence(P<0.05),vascular conditions showed no statistically significant difference(P>0.05);Implanted placenta previa with disc signal uneven,placental vessels in enlargement,T_(2)W1 placenta article within the ribbon is no clear boundary between low signal,placenta and uterus image features higher than that of patients with implanted with placenta previa not(P<0.05),placenta previa with convex,bladder bumps into the uterus contour outside the local image features less than patients with implanted with placenta previa not(P<0.05).Conclusion:MRI can improve the diagnostic efficiency of placenta previa and placental implantation,and is of great significance to formulate a reasonable treatment plan in clinic.
