摘　　要：目的探讨多模态MRI在胎盘植入(PA)诊断中的应用价值。方法回顾性分析62例经临床术中诊断或术后病理证实的PA患者的影像学资料,将多模态MRI与临床术中诊断或术后病理结果进行对比,评价多模态MRI对PA的诊断准确性。结果62例PA中,多模态MRI结果为粘连型10例、植入型39例、穿透型13例。临床术中诊断或术后病理结果为粘连型10例、植入型40例、穿透型12例。多模态MRI与临床术中诊断或术后病理一致性良好,总体准确率达88.7%。以临床术中诊断或术后病理为“金标准”,多模态MRI诊断粘连型、植入型和穿透型PA的准确率分别为87.10%、88.71%、91.94%;敏感度分别为70.00%、92.50%、91.67%;特异度分别为94.00%、85.71%、97.87%,Kappa值分别为0.640、0.815、0.848。结论多模态MRI在诊断PA中具有较高的准确率,可以作为临床工作中PA的常规检查方法。Objective To investigate the application value of multimodality MRI in diagnosing placenta accreta(PA).Methods The imaging data of 62 patients with PA confirmed by clinical intraoperative diagnosis or postoperative pathology were analyzed retrospectively,and the diagnostic accuracy of multimodality MRI for PA was assessed by comparing multimodality MRI manifestations with clinical intraoperative diagnosis or postoperative pathology findings.Results According to the multimodality MRI findings,62 cases of PA were divided into adhesive PA(n=10),implanted PA(n=39),and penetrating PA(n=13).According to the clinical intraoperative diagnosis or postoperative pathology,62 cases of PA were divided into adhesive PA(n=10),implanted PA(n=40),and penetrating PA(n=12).The multimodality MRI manifestations were in good agreement with clinical intraoperative diagnosis or postoperative pathology,with an overall accuracy of 88.7%.Taking clinical intraoperative diagnosis or postoperative pathology as the“gold standard”,the accuracy of multimodality MRI in diagnosing adhesive PA,implanted PA,and penetrating PA were 87.10%,88.71%,and 91.94%,respectively;the sensitivity were 70.00%,92.50%,and 91.67%,respectively;and the specificity were 94.00%,85.71%,and 97.87%,with Kappa values of 0.640,0.815 and 0.848,respectively.Conclusion Multimodality MRI has a high accuracy in diagnosing PA and can be used as a routine screening method for PA in clinical practice.
