摘　　要：目的探讨彩色多普勒超声(US)联合磁共振(MRI)成像对产前胎盘植入(PIA)及分型的诊断价值。方法选取2016年12月~2018年12月我院收治并经病理证实的100例PIA患者为对象,所有患者均行US、MRI及US联合MRI检查,以病理结果为金标准,对比不同检查方式对产前PIA及分型的诊断价值。结果 US联合MRI成像诊断产前PIA的敏感度为94.95%、特异度为93.94%、准确度为94.00%、阳性预测值为94.44%、阴性预测值为94.90%,均显著高于US诊断和MRI成像诊断,误诊率和漏诊率均低于US诊断和MRI成像诊断(P<0.05);US联合MRI成像对产前PIA中Ⅰ型诊断率为82.86%,Ⅱ型为93.48%,Ⅲ型为68.42%,均显著高于US诊断和MRI成像诊断(P<0.05),且与病理诊断比较无统计学意义(P>0.05)。结论 US联合MRI成像对产前PIA及分型的诊断价值高于单独诊断,值得临床进一步推广。Objective To investigate the diagnostic value of color Doppler ultrasound(US)combined with magnetic resonance imaging(MRI) in prenatal placental implantation abnormality(PIA) and typing.Methods 100 patients confirmed with PIA by pathology who were admitted to the hospital from December 2016 to December 2018 were enrolled.All patients underwent US,MRI and US combined MRI.Taking the pathological results as golden standard,the diagnostic value of different examination methods for prenatal PIA and typing was compared.Results The sensitivity,specificity,accuracy,positive predictive value and negative predictive value of US combined with MRI for prenatal PIA were94.95%,93.94%,94.00%,94.44% and 94.90%,respectively.Which were significantly higher than those of US or MRI.And the misdiagnosis rate and missed diagnosis rate were lower than those of US or MRI(P<0.05).The diagnosis rates of US combined MRI for type Ⅰ,type Ⅱ and type Ⅲ prenatal PIA were 82.86%,93.48% and 68.42%,respectively.Which were significantly higher than those of US or MRI(P<0.05).There was no statistical significance compared with pathological diagnosis(P>0.05).Conclusion The diagnostic value of US combined MRI is higher than that of either of them for prenatal PIA and typing,which is worthy of further clinical promotion.
