摘　　要：目的分析超声检查与磁共振成像(MRI)在凶险型前置胎盘(PPP)诊断中的图像特征。方法选取2017年8月—2020年4月江苏省常州市中医医院经术后病理确诊为PPP患者60例。以术后病理诊断结果为金标准,对比超声及MRI诊断结果,并分析其图像特征。结果术后病理确诊合并胎盘植入50例;超声诊断合并胎盘植入42例;MRI诊断合并胎盘植入45例,超声联合MRI诊断合并胎盘植入48例。联合检查诊断PPP准确性、敏感度、特异性、约登指数、AUC值分别为90.00%、92.00%、80.00%、0.72、0.93,均高于单一检查方式,差异有统计学意义(P<0.05)。结论PPP患者超声及MRI影像图表现均有特征性,且超声联合MRI检查有助于提高PPP的诊断准确性。Objective To analyze the image characteristics of ultrasonography and magnetic resonance imaging(MRI)in the diagnosis of dangerous placenta previa(PPP).Methods Sixty patients with PPP confirmed by postoperative pathology in Changzhou Hospital of Traditional Chinese Medicine from August 2017 to April 2020 were selected.With postoperative pathological diagnosis as the gold standard,the ultrasound and MRI diagnosis results were compared,and the image characteristics were analyzed.Results A total of 50 cases were confirmed by postoperative pathology with placental implantation;ultrasonography was used to diagnose 42 cases with placental implantation;MRI diagnosis of 45 cases with placental implantation,and ultrasonography combined with MRI was used to diagnose 48 cases with placental implantation.The PPP accuracy,sensitivity,specificity,Yoden index and AUC values of the joint examination were 90.00%,92.00%,80.00%,0.72 and 0.93,respectively,which were all higher than the single examination method,with statistically significant differences(P<0.05).Conclusion Both ultrasound and MRI images of PPP patients have characteristics,and ultrasound combined with MRI is helpful to improve the diagnostic accuracy of PPP.
