Figure 4.
Color-coded fractional anisotropy (FA) maps, with red = right–left, green = anterior– posterior, blue = superior–inferior. In three axial slices, the dashed lines and arrows highlight regions with severe susceptibility-induced distortions and eddy current-induced FA errors, respectively [162]. A = no correction. B = static correction; C = dynamic correction. Adapted with permission from Neuroimage, Volume 57/Issue 4, T.-K. Truong, N.-k. Chen, & A. W.
