Abstract : Introduction: Placenta Previa (PP) is a pathological condition defined as displacement of placenta to the cervical region. The purpose of this study is to evaluate the superiority of magnetic resonance imaging (MRI) over ultrasound (US) in diagnosing placenta Previa (PP) in the second stages of pregnancy and to determine morbidity association with PP. Materials and Methods: This retrospective study includes 65 cases of pregnant women with PP. The cases we collected from six different hospitals in Riyadh. The results of MRI and US of PP cases compared with post-operative data. The patients’ files reviewed for assessment. Results: Chi-square and Cross-tabulation statistical tests used. The Statistical information of PP patients shows that age group 29-39 have the highest frequency of PP with associated grade IV, and there is significant Relation between age and grade where P= 0.001% < 0.05 % (from chai square test). Result shows that the degree of PP is age dependent. Increta association has highest frequency with PP on imaging MRI modality. Almost half of the cases have no association with PP. These results are evidence that MRI is superior in diagnosing PP over US. Conclusions: The MRI and US are the prime choices for diagnosing abnormal placentation. MRI has the superiority in diagnosing PP over US based on the collected medical reports and reviewed MRI as well as US image. The results of this study indicate that the relationship between age and PP grade complication is s
