Federated learning boosts brain health prediction from MRI scans

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a federated learning approach to estimate Brain-Predicted Age Difference (BrainAGE) from MRI scans of stroke patients, addressing privacy concerns that typically hinder large-scale neuroimaging studies. This method, tested across 16 hospital centers with 1674 patients, demonstrated that federated learning models performed better than single-site models, though not as accurately as centralized learning. The study found a significant association between higher BrainAGE, vascular risk factors like diabetes, and poorer functional outcomes three months post-stroke, suggesting BrainAGE's utility in prognostic modeling for stroke care.

    Federated Learning for MRI-based BrainAGE: a multicenter study on post-stroke functional outcome prediction

    arXiv:2506.15626v3 Announce Type: replace-cross Abstract: $\textbf{Objective:}$ Brain-predicted age difference (BrainAGE) is a neuroimaging biomarker reflecting brain health. However, training robust BrainAGE models requires large datasets, often restricted by privacy concerns. T…
