RegionFM framework enhances interpretability of foundation models for brain MRI classification

Researchers have developed RegionFM, a novel framework designed to enhance the interpretability of foundation models used in brain MRI classification. This approach integrates anatomical segmentation with foundation model embeddings, allowing for the explicit quantification of individual brain region contributions to predictions. RegionFM divides MRI scans into anatomical regions, encodes each region into an embedding using a frozen foundation model, and then uses a region-additive logistic model to combine these embeddings for classification. Evaluations on cognitive impairment classification demonstrate that RegionFM achieves performance comparable to less interpretable fine-tuning methods while providing anatomically grounded explanations.
