Synopsis

Keywords: Placenta, Radiomics, placenta accreta spectrum, MR images, hysterectomyPlacenta accreta spectrum (PAS) is associated with significant morbidity and mortality. We applied ROI-based radiomics analysis on axial and sagittal plane MR images in women with placenta previa and a history of previous cesarean delivery. Our goal was to compare MR textural features extracted from axial and sagittal imaging planes and compare findings to surgical outcomes. Radiomics features were significant in both anatomical planes in the MRIs of women who underwent hysterectomy.
