Fig. 3 — Qualitative and quantitative quality-assurance measures following dMRI preprocessing. (a) Representative mid-axial images of the fractional anisotropy (FA) (red-yellow) image overlaid on the ‘acpc aligned’ anatomical (T1w) image. Images were generated using brainlife.app.309. (b) The signal-to-noise ratio for each participant from each group (football: orange, cross-country: pink, non-athlete: blue) following dMRI preprocessing. The average SNR was computed in the Corpus Callosum across the b = 0 shells (crosses) and b = 1000,2000 shells (circles). Standard deviation across the non-b = 0 shells are plotted as error bars for each participant.
