Abstract Placenta accreta has a high potential for hysterectomy, with a maternal death rate reported at 7%. Morbidly adherent placenta may lead to massive obstetric haemorrhage resulting in complications such as disseminated intravascular coagulopathy, need for hysterectomy, injury of urinary tract and other viscera, adult respiratory distress syndrome, renal failure and even death However, antenatal diagnosis is the single most important factor in improving the outcome in MAP, via high degree of clinical suspicion along with ultrasound and MRI. In this study, MRI was found to have a greater diagnostic accuracy of 86.2 %in diagnosis of placenta accreta in comparison with Doppler US which has a diagnostic accuracy of 74.1%. In this study, the most common ultrasound features in predicting placenta accreta were the presence of placental lacunae, the loss of retro-placental sonolucent zone, The most dominant color Doppler finding in the current study was the presence of increased amount of blood vessels and turbulent blood flow, with 85.4% sensitivity, 47.1% specificity, both PPV and NPV were 79.5% and 57.1%, respectively, with diagnostic accuracy 74.1%. In this study, the most common MRI features in predicting placenta accreta were the presence of uterine bulge and heterogenous signal intensity within the placenta with 97.6% sensitivity, 58.8% specificity, both PPV and NPV were 85.1% and 90.9%,. |
