Abstract:
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.
