Foundation models address these limitations by learning reusable representations from large-scale data, often through self-supervised or contrastive pretraining, and adapting them to multiple downstream tasks. Emerging models in electrocardiography, echocardiography, chest radiography, cardiac MR and cardiac CT demonstrate capabilities including disease classification, quantitative measurement, segmentation, image-text retrieval, report generation and risk prediction.
