Abstract
Purpose: Todetermine the value of magnetic resonance imaging (MRI) findings in the prenatal diagnosis of placenta accreta (in comparisonwith surgical and pathologicdiagnosis).
Methods: All gravid women suspected placenta accreta on ultrasound underwent MRI and cesarean delivery from 01/2017 to 06/2022 at Tu Du Hospital. All cases have medical records andimages at radiology department. MRI findings were compared with surgical and pathologic diagnosis
Results: MRIfindings have high value in the prenatal diagnosis of placenta accreta include loss of T2 hypointense interface (in 92% of patients with this finding, there was 97,5% placenta accreta, Sn 94%, Sp 50%), placenta previa (in 88% of the patients with this finding, there was 95,9% placenta accreta, Sn 84,3%, Sp 25%), focal interruption in myometrial wall (in 77% of patients with this finding, there was 100% placenta accreta, Sn 80,7%, Sp 100%) and intraplacental T2 - dark bands (in 73,6% of patients with this finding, there was 100% placenta accreta, Sn 77,1%, Sp 100%)
Conclusion: MRI findings in the prenatal diagnosis of placenta accreta have high sensitivity and specificity. Therefore, MRI is useful method to support ultrasound in cases difficulty to evaluate placenta on ultrasound orinvasive placenta with extrauterine spread.
