Table 2. Correlation coefficients (r) of DTI parameters vs. age, averaged over WM skeleton.
The parameter with the greatest correlation with age, f, is shown in bold. All correlations significant at p<0.05 except for MDt. Key: AD, axial diffusivity; DTI, Diffusion tensor imaging; FA, fractional anisotropy; MD, mean diffusivity; RD, radial diffusivity; WM, white matter.
