ACCURACY OF MULTI-SLICE 3D-DOPPLER IN DIAGNOSIS OF MORBIDLY ADHERENT PLACENTA IN COMPARISON WITH 2D-DOPPLER

Background: Morbidly adherent placenta can be diagnosed prenatally by different modalities. 2D, 3D multi-slice Doppler ultrasound and MRI have emerging roles in prenatal diagnosis of morbidly placenta, but histopathological is the gold standard.Aim work: To detect accuracy over 2D-Doppler accreta relation to postpartum histopathology intrapartum findings.Patients Methods: This study was conducted at Ain shams university maternity hospital during period between March 2020 September 2020. A total 50 pregnant women having Previa were included study. Patients according following criteria: Pregnant with history previous cesarean section or hysterotomy, previa its lower edge covering scar section, From 28 wks – Full term.Each patient scanned a systematic fashion 2D ultrasonography, 2D-Doppler, Multislice 3D-Doppler preoperatively results compared examination postoperatively.Results: Crowded vessels peripheral sub-placental zone had highest diagnostic characteristics among multislice signs placental invasion postoperative (sensitivity 95.2%, specificity 93.1%, PPV 90.9%, NPV96.4%, LR 270.00).Hyper vascularity serosa–bladder interface ultrasonography 90.5%, 89.7%, 86.4%, NPV 92.9%, 82.33).Conclusion: Multi-slice more accurate than accrete degree adherence findings.
