When do anatomical priors help? Missing-modality robustness in small-sample dual-modal brain MRI region segmentation

Anatomical priors are often assumed to improve medical image segmentation, but their role can be ambiguous when strong image evidence is available. We study this question in a controlled small-sample dual-modal brain MRI setting with 13-class coarse brain-region segmentation from T1 and FLAIR images. Using a quality-co...
