BrainDINO: A Brain MRI Foundation Model for Generalizable Clinical Representation Learning

Chih-Wei Chang, Harini Veeraraghavan, Mingzhe Hu, Mojtaba Safari, Shansong Wang, Xiaofeng Yang, Yizhou Wu, Yuheng Li

A self-supervised model trained on millions of brain MRI slices yields a unified representation that supports diverse clinical tasks with a frozen encoder and lightweight heads.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

a single self-supervised representation can generalize across heterogeneous brain MRI endpoints... large-scale slice-wise self-supervised learning can yield a unified brain MRI representation that supports diverse neuroimaging tasks without volumetric pretraining or full-network fine-tuning

C2weakest assumption

That the 20 datasets and the selected clinical endpoints (tumor segmentation, classification tasks, survival modeling, etc.) are sufficiently representative to support the claim of broad generalizability across all brain MRI applications and acquisition settings.

C3one line summary

BrainDINO delivers a single self-supervised brain MRI representation that generalizes to tumor segmentation, disease classification, brain age estimation, and other tasks without volumetric pretraining or full fine-tuning.
