Abbreviations: CIDP = chronic inflammatory demyelinating polyneuropathy; MMN = multifocal motor neuropathy; FA= fractional anisotropy; MD = mean diffusivity; AD = axial diffusivity; RD = radial diffusivity; T2 = T2 relaxation time; ms = milliseconds; FF = fat fraction; Mean D = mean difference; p = p value; r = Pearson’s correlation coefficient; * = correlation is significant. MD, AD and RD values are x10 -3 mm 2 /s.
