AD Axial diffusivity, MD Mean diffusivity, RD Radial diffusivity, FA Fractional anisotropy, SCP Superior cerebellar peduncle, MCP Middle cerebellar peduncle, ICP Inferior cerebellar peduncle, * Statistical significance was set at p<0.0083, (Bonferroni corrected p<0.05). The MD, RD, and AD metrics are shown as 10-3, and FA is shown as the actual value. Note that only the right inferior cerebellar peduncle displayed significant increases in MD, RD, and AD compared with controls.
