Objectives: To evaluate the accuracy of magnetic resonance imaging in assessment and characterization of placental implantation disorders in pregnant females with placenta previa. Methods: This research was carried out during period from July 2017 to June 2019 incorporated 90 pregnant females with placenta previa. The findings of MR imaging in abnormal placentation were compared with post-operative information and our results from statistical analysis were proportionated to those from the literature. Results: Out of 90 pregnant women with placenta previa, 21 cases had abnormal placentation at MRI and post-operatively, 8 cases with placenta accreta, 3 with increta and 10 with percreta. MRI has 100 % sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV). Conclusion: MRI was highly accurate in recognition of myometrial invasion and type of anomalous placentation with high sensitivity in diagnosis of abnormal placentation, proper assessment in pre-operative diagnosis of placental invasion and thus reducing morbidity rate and improving outcome.
