Representative DW-MRI images. All images acquired at the same proximal-distal level, approximately halfway between the proximal and distal tibial epiphyses, in the right leg of a single, representative participant. a-d Diffusion-weighted images acquired at progressively increasing diffusion-probing gradient strength: (a) b = 0 s/mm2, (b) b = 100 s/mm2, (c) b = 300 s/mm2, and (d) b = 500 s/mm2. e logarithm of signal intensity is plotted as a function of diffusion-probing gradient strength in a single participant. f ADC map for the same participant at (a-e). g, h ADC maps for the right and left legs of a representative participant with spinal cord injury. Abbreviations: TA, Tibialis Anterior; SOL, Soleus; LG, Lateral Gastrocnemius; MG, Medial Gastrocnemius
