Comparing Baseline and Day-1 Diffusion MRI Using Multimodal Deep Embeddings for Stroke Outcome Prediction
The study compared baseline (J0) and 24-hour post-stroke (J1) diffusion MRI to predict three-month functional outcomes after acute ischemic stroke. J1 imaging showed superior predictive power, achieving an AUC of 0.923, significantly better than J0 configurations. Integrating deep MRI embeddings with clinical and lesion volume features created a robust model that is both highly accurate and interpretable.
