...Typical qMRI markers for FVF are based on: (i) Neurite orientation dispersion and density imaging (NODDI) [Zhang et al., 2012] as used, for example, in Stikov et al. [2015] and (ii) tractfiber density (TFD) [Reisert et al. 2013], as used in Mohammadi et al. [2015], or (iii) the diffusion tensor…...
