Figure 1

Visualizes a side-by-side comparison between T1-weighted images (left side, column A), the calculated MWF maps (middle, column B) and MWI heat maps (right side, column C). An example for ROI localization is given in column A. The scale on the right side indicates the estimated MWF values. Higher MWF values are indicated by the range of “warm” (red) colours, whereas lower MWF values are indicated by the range of “cold” (blue) colours. ROIs were placed in both corticospinal tracts (section A2), frontal and occipital white matter (WM) and genu- and splenium of corpus callosum (section A3) and the parietal WM of both hemispheres (section A5).
