Understanding Sources of Demographic Predictability in Brain MRI via Disentangling Anatomy and Contrast
The episode discusses a paper titled "Understanding Sources of Demographic Predictability in Brain MRI via Disentangling Anatomy and Contrast." Researchers found that demographic predictability in brain MRI is primarily driven by anatomical structure, not scanner contrast. The anatomy-focused representations maintained most predictive power across datasets, while contrast embeddings showed site-specific fragility.
