前置胎盘伴胎盘植入的磁共振影像学特征分析

Analysis of Magnetic Resonance Imaging Features of Placenta Previa with Placental Implantation

目的:分析前置胎盘伴胎盘植入的磁共振(MR)影像学特征.方法:选取2017年11月-2018年11月本院收治的前置胎盘伴胎盘植入患者60例,均进行MR检查,并以手术病理诊断结果为金标准,计算MR诊断符合率,分析MR的影像学特征.结果:手术病理确诊率为100%,MR确诊率96.67%,两种方法确诊率比较,差异无统计学意义(P>0.05);MR确诊的58例患者中边缘型前置胎盘18例(31.03%)、部分型前置胎盘22例(37.93%)、中央型前置胎盘18例(31.03%),侵入性胎盘20例(34.48%)、穿透性胎盘19例(32.76%)、粘连性胎盘19例(32.76%).结论:MR在前置胎盘伴胎盘植入诊断中的准确性较高,不易受其他因素影响,患者易于接受,临床价值较高,值得借鉴、推广.

Objective:To analyze the magnetic resonance(MR)imaging features of placenta previa with placental implantation.Method:A total of 60 patients with placenta previa with placental implantation admitted to our hospital from November 2017 to November 2018 were selected.All patients underwent MR examination, the results of pathological diagnosis were the gold standard,the coincidence rate of MR diagnosis was calculated and the imaging characteristics of MR were analyzed.Result:The diagnostic rate of operation and pathology was 100% and that of MR was 96.67%,there was no significant difference in the diagnostic rate between two methods (P>0.05).Of the 58 patients diagnosed by MR,18 cases(31.03%)of marginal placenta previa,22 cases (37.93%)of partial placenta previa,18 cases(31.03%)of central placenta previa,20 cases(34.48%)of invasive placenta,19 cases(32.76%)of penetrating placenta,19 cases(32.76%)of adhesion placenta. Conclusion:MR has high accuracy in the diagnosis of placenta previa with placental implantation,it is not easily affected by other factors,it is easy for patients to accept and has high clinical value,it is worth learning and popularizing.
