1) The study explored how microstructural maps from diffusion MRI scans of stroke patients correlate with Fugl-Meyer motor assessment scores. 2) The best correlation was found between the Orientation Dispersion Index from NODDI modeling and inverse Fugl-Meyer scores, suggesting it captures microstructural changes following stroke. 3) Scaling the divergence between ipsilesional and contralesional regions by stroke volume increased correlation for some maps, indicating it may provide a more sensitive measure of severity.
