White Matter Structural Differences in Voxel Based

Differences in voxel-based and TBSS-based FA values between PD-aMCI and PD-CN

Compared to PD-CN, PD-aMCI showed smaller fractional anisotropy (FA) values. The smaller voxel-based FA values A) and TBSS-based FA values B) were located in the brain areas superimposed on a series of sagittal slices ranging from 46 mm to -46 mm at x-axis (from right to left), with an interval of 4 mm. The color bar indicates the 1-p value ranging from 0.95 to 1. In B), the significant TBSS-based FAs (in red) were dilated to enhance visualization, overlaying on the white matter skeleton (in green).
