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.
