Development and validation of a versatile foundation model for cine cardiac magnetic resonance image analysis
Cardiac magnetic resonance imaging (CMR) is crucial for diagnosing and managing cardiovascular diseases, but current analysis methods are slow, subjective, and lack reproducibility. Traditional deep learning models need separate training for each task and extensive labeled data. This paper introduces CineMA, a multi-view conv-transformer masked autoencoder foundation model, pre-trained on 15 million cine CMR images from 74,916 studies. CineMA was fine-tuned and evaluated on eight independent datasets for segmentation, landmark localization, disease diagnosis, and prognostication. It demonstrated accuracy, learning efficiency, adaptability, and fairness across diverse tasks, matching or exceeding specialized CNN baselines, especially in low-data settings and across population shifts. CineMA offers a strong alternative to task-specific models for automated cardiac image analysis, with all code and models freely available.
Executive Impact
CineMA's foundation model for cardiac MRI analysis significantly reduces manual effort, standardizes assessments, and improves diagnostic consistency across diverse clinical settings and patient populations. This leads to faster, more reliable cardiovascular diagnoses and prognoses, thereby enhancing clinical workflow efficiency and supporting multi-centre studies and longitudinal monitoring.
