Prognosticating Maternal and Neonatal Outcomes in Placenta Accreta Spectrum Disorders by Combining Placental Perfusion and MRI Features

Motivation: The factors to predict adverse maternal and neonatal outcomes in patients with placenta accreta spectrum disorders needed identification. Goal(s): This study aimed to identify appropriate predictive indicators using magnetic resonance imaging (MRI) and intravoxel incoherent motion (IVIM) parameters. Approach: The study examined the association between various influencing factors (clinical risk factors, MRI features, and IVIM parameters) and adverse outcomes using univariate and multivariate analyses. Results: Independent predictors of a poor prognosis included previous cesarean sections, low-signal-intensity bands on T2WI, and D value. Impact: The components of the prediction model in this study were more comprehensive and improved the prediction efficiency. The study analyzed the relationship between f value and postpartum hemorrhage and further examined the importance of IVIM in predicting adverse outcomes.
