Key result

HSCM-Net achieves a 0.577 Dice score for myocardial pathology segmentation on unseen multisequence CMR images.

Why the study?

Existing deep learning methods for myocardial pathology segmentation show limited generalizability across domains due to distribution shifts and difficulty learning domain-invariant pathology information.

Population

Three-domain multisequence CMR datasets

Comparison

HSCM-Net framework concept modeling vs unseen target domains

Dong et al. (2026) studied Myocardial infarction. HSCM-Net (hierarchical semantic concept segmentation framework) was evaluated on MyoPS Dice score on unseen target domains. The HSCM-Net framework achieved a MyoPS Dice score of 0.577 on unseen target domains, demonstrating generalizability for myocardial pathology segmentation on multisequence CMR images.
