Diagnostic value of MRI in invasively pernicious placenta previa / 实用放射学杂志

ABSTRACT

Objective To explore the diagnostic value of MRI in invasively pernicious placenta previa.Methods MRI and color doppler ultrasound were performed in 1 50 patients with pernicious placenta previa.According to the operation or pathology findings, the diagnostic value of placental invasion was compared among MRI,color doppler ultrasound and both of them.Analyzed and com-pared the MRI findings of 64 patients which were confirmed as invasive placenta including adherent placenta in 20 patients,implanted one in 38 and penetrated one in 6.Results Significant difference was not found among MRI,color doppler ultrasound and both in the diagnostic value of invasive placenta (P >0.05).There was a significant difference among adherent placenta,implanted one and pen-etrated one in the diagnostic value of MRI (P <0.05),and the highest and lowest values were penetrated placenta and adherent pla-centa respectively.Conclusion MRI is an important diagnostic method in invasively pernicious placenta previa,which was useful for its classification but with a limitation for the diagnosis of adherent placenta.
