Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Prenatal diagnosis of invasive placentation is associated with a reduced risk of maternal complications as it allows a preplanned treatment of the condition . Gray-scale and colour Doppler ultrasound (US) are valuable tools in the prenatal diagnosis of placenta accreta .However, if the ultrasound ( US ) findings suggest possible percreta or are inconclusive or negative in an at-risk woman, magnetic resonance imaging (MRI) can be useful.
Multiple sonographic findings are seen with placenta accreta such as decrease in myometrial thickness, placenta previa, placental lacunae, abnormal pattern of color Doppler, loss of the retroplacental clear zone and placenta percreta irregularities in wall of urinary bladder ( UB ) have been detected .
The most magnetic resonance imaging characteristic findings seen in placenta accreta are nodular thickening in the dark zone of placenta-uterine interface together with extensions of dark bands through the placenta, outer uterine bulge causing from the mass effect of the placenta and heterogeneous signal intensity of placenta on the T2-weighted HASTE sequences due to large placental lakes and vessels.
