  • New AI Model Introduced: A new foundation model named BrainIAC has been developed to extract multiple disease risk signals from routine brain MRI scans.

  • Versatile Application: BrainIAC can estimate brain age, predict dementia risk, detect brain tumor mutations, and predict survival rates from brain cancer.

  • Training and Performance: The model was trained on nearly 49,000 brain MRI scans and outperformed other more task-specific AI models.

  • Self-Supervised Learning: Utilizes a self-supervised learning approach to identify inherent features from unlabeled datasets, enabling it to adapt to various tasks efficiently.

  • Efficiency with Limited Data: BrainIAC particularly excelled in scenarios where training data was limited or task complexity was high.

  • Diverse Validation Tasks: After pretraining on multiple imaging datasets, BrainIAC was validated on 48,965 brain MRI scans for seven different clinical tasks.

  • Potential Impact on Medicine: The model has the potential to accelerate biomarker discovery, enhance diagnostic tools, and integrate AI more broadly into clinical practice.

  • Funding and Support: The study received support from the National Institutes of Health/the National Cancer Institute and Botha-Chan Low Grade Glioma Consortium.
