Diffusion MRI - analysis pipeline and initial results for fractional anisotropy. A. Schematic figure representing the raw data (b=0) for both anterior-to-posterior and posterior-to-anterior encoding directions (A) and after application of the two reversed phase encoding (B). Red circles show before and after correction for distortions. Diffusion MRI (dMRI)-derived metrics for fractional anisotropy (FA) and mean diffusivity (MD) are also shown (C). R and L define the right and the left hemisphere, respectively. B. Histogram of mean fractional anisotropy in the first 300 participants.
