[Abstract] Objective: To analyze the features and diagnostic value of MRI in placenta implantation abnormality (PIA).Materials and Methods: Sixty-five cases placenta previa underwent MRI scans, compare with comfirmed clinically or pathologically, obtained the sensitivity, accuracy and analyze the MRI appearances.Results: Placenta accreta was found in 12 cases, placenta increta in 18 cases. The direct signs of PIA were as follows: the bottom of decidual low signal being blurred or interrupt, myometrium becoming thinner or interrupted. The indirect signs of PIA were as follows: lower uterine segment bulging, local thickening and heterogeneous signals of placenta, the intraplacenta vascularity becoming thickening and increasing. The sensitivity, specificity, positive predictive value, negative predictive value were 90.9%, 89.7%, 88.2%, 92.1%.Conclusion: MRI has a high diagnostic value for PIA, and it can guide the clinical to maka effective treatment and reduce the complications.
