Curriculum-guided framework enhances myocardial scar segmentation on cardiac MRI

A curriculum learning approach for LGE-CMR scar segmentation outperforms standard training, particularly in cases with minimal or diffuse scar. The progressive training strategy guides the model from high-confidence to low-confidence regions, improving robustness.

• The method uses a progressive training strategy, moving from high-confidence, clearly defined scar regions to low-confidence or ambiguous samples with limited scar burden.
• The approach improved segmentation accuracy and consistency over standard baselines, with the largest gains seen in challenging minimal or diffuse scar cases.
