Abstract
Using ultrasonography (2D grey scale, color Doppler and 3D power Doppler) and magnetic resonance imaging for the prenatal diagnosis of placenta accreta in women who have had a previous caesarean section scar and are pregnant between 34 and 37 weeks of pregnancy.
Individual ultrasonographic and magnetic resonance imaging markers were compared for sensitivity and specificity in the prediction of placental invasion in cases with placenta accreta between 34 and 37 weeks of pregnancy.
Methods:
75 pregnant women between the ages of 34 and 37 weeks of pregnancy were admitted to Kasr Al Ainy hospital due to suspected placental invasion and/or adherence to outpatient clinic 2 D ultrasound guidelines. The state of the placenta was verified intra-operatively by the surgeon and validated by pathology, prenatal diagnosis using greyscale ultrasonography, colour Doppler, 3D power Doppler, and magnetic resonance imaging was done.
Results:
Pathological testing verified placenta accreta variants (including accreta, increta, and percreta) in 55 of the 75 individuals. We compared greyscale ultrasound to 3D power Doppler and magnetic resonance imaging for placenta accreta spectrum diagnosis and found that while both are effective tools for diagnosis, ultrasonography had marginally higher sensitivity, specificity, and accuracy than MRI.
Conclusion:
Although magnetic resonance imaging can be used in conjunction with ultrasound (grey scale, color Doppler, and 3D power Doppler) for the prenatal diagnosis of placenta accreta, it cannot replace ultrasonography as a screening diagnostic for placenta accreta.
