DTI metrics of the deep grey matter structures.

Data are expressed as mean±SD. * p-values (general linear model) refer to comparison between all MS patients and controls. Significance p-values for comparison between RR-MS patients and controls are reported in parentheses. Abbreviations: Fractional Anisotropy (FA), Mean Diffusivity (MD), Multiple Sclerosis (MS), Relapsing Remitting (RR), Secondary Progressive (SP). FA is a scalar value between 0 and 1. MD is expressed in µm2/s.
