Quantitative T2 measured in our dystrophic mouse model has shown distinct dystrophic pathology that correlates with histological measurements at young, but not older ages. Here we explored the role of regenerating muscle fibers in altering T2 measurements in muscle and sought to identify other parameters to provide complimentary information about the cascade of events occurring after muscle damage. We find that DTI and fiber tracking is a promising means to evaluate muscle fiber regeneration and dystrophic pathology.
