Fig 2.
The main values of the axial diffusivity, radial diffusivity, and FA from all 8 regions of interest are shown. A significant reduction (P < .0001) of both axial and radial diffusivities and elevation (P < .0001) of FA are observed from neonates to 1-year-olds. The changes from 1- to 2-year-olds are more subtle for both axial diffusivity and FA, whereas a significant reduction (P = .0014) in radial diffusivity is observed. The labels for the left and right y-axis represent the directional diffusivities and FA, respectively.
