Comparing The Diagnostic Value Of Magnetic Resonance Imaging (Mri)With Colour-Doppler Ultrasound For Placenta Accreta

Placenta adhesive disorder (PAD) is one of the most common causes of postpartum hemorrhage and peripartum hysterectomy. The main risk factors are placenta Previa and prior uterine surgery such as cesarean section. Diagnosis of placenta adhesive disorders can lead to a decrease of maternal mortality and morbidities.
 Material and Methods:
 In this cross-sectional study, Seventy-nine pregnant women who were high risk for PAD and had inclusion criteria underwent color Doppler ultrasound and MRI. The sonographic and MRI findings were compared with the final pathologic or clinical findings. P  Result:
 Mean maternal age was 32.9894.8 years. The history of the previous cesarean section was seen in 68 cases (86%) and 11 patient had curettage. The diagnosis of placenta accrete was found in 45 cases (57%). Doppler sonography sensitivity was 91% and MRI sensitivity was 73.3% , Doppler sonography specificity was 64.7% and MRI specificity was 79.4%.
 Women with high-risk factors for PAD should undergo Doppler ultrasonography at first. When results on Doppler sonography are equivocal for PAD, MRI can be performed due to its high specificity.
