New Framework Aligns CT and EHR Data for Improved Time-to-Event Prediction

Researchers have developed a new framework for cross-modal representation alignment to improve time-to-event (TTE) prediction using both CT imaging and longitudinal electronic health records (EHR). This foundation model-driven approach addresses challenges like modality imbalance and distribution shift by aligning data in a shared latent space through various fusion strategies. The framework demonstrated consistent improvements in prediction accuracy across different TTE tasks, particularly for pulmonary embolism mortality, with contrastive multimodal fusion showing robust results.
