Copyright © 2018 by Türkiye Klinikleri.Objective: The present study evaluated the ability of magnetic resonance imaging (MRI) andultrasonography (US) in diagnosing placenta accreta in cases of anteriorly localized placenta previa with a high risk of placental adhesion abnormality. Material and Methods: A total of 29 patients with anteriorly localized placenta previa and having at least one risk factor for placenta accreta underwent US and MRI. Diagnostic ability of both modalities for the prediction of abnormal placental invasiveness was assessed using various imaging signs described in the existing literature. Results: Of the 29 pregnancies with placenta previa, 13 (44.8%) had placenta accreta that was confirmed at the time of surgery. Cesarean hysterectomy was performed in seven (53.8%) cases. Sensitivity, specificity, and diagnostic accuracy of ultrasound and MRI were calculated to be 84.6%, 81.2%, and 82.7% and 100%, 76.9%, and 86.2%, respectively. In 5 of 29 cases, US and MRI had discordant diagnoses; sonography detected placenta accreta in 2 cases, whereas magnetic resonance imaging predicted it in 3 cases. Conclusion: The diagnostic abilities of ultrasound and MRI for the detection of placenta accreta appear to be comparable. Magnetic resonance imaging may be required to plan the surgical approach and assess the risk of potential surgical morbidity.
