The Bland–Altman plots. Difference versus sum for FA (scaled 0–1) and ADC (10-3mm2/s) measured by circular (C) and freehand (F) methods. The Bland–Altman plots show maximum and minimum differences of regions with 95% limits of agreement (dotted lines): genu of the corpus callosum (FA) (a), centrum semiovale (FA) (b), posterior limb of the internal capsule (ADC) (c) and basal pons (ADC) (d).
