ABSTRACT
Objective To explore MRI features in diagnosis of placenta accrete(PA).Methods MRI images of 19 patients with PA and 14 normal subjects were reviewed retrospectively.MRI features of the placenta and adjacent structures were analyzed and compared.Results Compared to the MRI findings of the normal subjects,abnormal uterine bulging,heterogeneous signal intensity of the placenta,and hypo-intensity intraplacental bands on T2WI were significantly higher in the patients with placenta accrete (P= 0.000,P=0.003 and P=0.015,respectively).The sensitivity,specificity,positive predictive value,negative predictive value and accuracy of the three features diagnosing placenta accrete were 78.95%,85.71%,88.24%,75.00%,81.82%;84.21%,71.43%,80.00%, 76.92%,78.79%;73.68%,71.43%,77.78%,66.67% and 72.73%,respectively.Conclusion MRI has important value in diagnosing PA.The MRI features of abnormal uterine bulging,heterogeneous signal intensity within the placenta,and hypo-intensity intraplacental bands on T2WI are useful for diagnosis.
