Results of ROI based analysis. Median FA (a), MD (b), AD (c), and RD (d) measured in ROI in the uninjured nerve, the distal stump and the proximal stump, at different b-values and of the multi-shell approach. Friedmans Test confirmed that MD, AD, and RD decreases with increasing b-value in the distal stump. The same was seen for AD and RD concerning the uninjured nerve. Error bars indicate the interquartile range of ROI measurements. P-values presented at the top represent Friedmans test of variations within the group. Asterisks indicate a statistically significant difference compared to the uninjured nerve.
