Background: Placenta accreta has now become an important etiology of maternal morbidity and mortality. Owing to the increasing rate of Cesarean delivery, there has been a 10-fold rise in the incidence of placenta accreta since the 1970s.
 
Objectives: to emphasize the diagnostic value of different imaging modalities (Doppler US and MRI) as noninvasive methods in diagnosis of adhesive placental abnormalities.
 
Patients and methods: A prospective study, conducted in Qena university hospital, South Valley University, Qena, Egypt. The study was conducted on  20 pregnant women has presented  with adhesive placental disorders to diagnostic radiology department.All included pregnant female will be subjected to history taking and clinical provisional examination. They will undergo doppler ultrasonography and MRI.
 
Results:  Sensitivity, specificity, accuracy of US was 72.7, 77.8, 75 respectively. But sensitivity, specificity, accuracy of MRI was 100,100,100 respectively.
 
Conclusion: Magnetic resonance imaging is better than  Doppler ultrasound study for the accurate diagnosis of placenta adherence/ invasion.
