Towards an accurate and generalizable multiple sclerosis lesion segmentation model using self-ensembled lesion fusion

no code implementations3 Dec 2023 Jinwei Zhang, Lianrui Zuo, Blake E. Dewey, Samuel W. Remedios, Dzung L. Pham, Aaron Carass, Jerry L. Prince

Automatic multiple sclerosis (MS) lesion segmentation using multi-contrast magnetic resonance (MR) images provides improved efficiency and reproducibility compared to manual delineation.

Lesion Segmentation Segmentation

Harmonization-enriched domain adaptation with light fine-tuning for multiple sclerosis lesion segmentation

no code implementations31 Oct 2023 Jinwei Zhang, Lianrui Zuo, Blake E. Dewey, Samuel W. Remedios, Savannah P. Hays, Dzung L. Pham, Jerry L. Prince, Aaron Carass

Our experiments illustrate that the amalgamation of one-shot adaptation data with harmonized training data surpasses the performance of utilizing either data source in isolation.
