Microstructural modelling. (a) The MD, FA, and DEC derived from the tensor were fitted to a single-shell (b = 1000 s/mm2) DTI model using FSL’s dtifit. (b) The OD, Vic, and Viso parameters were obtained by fitting a multi-shell (b = 1000, 2000, 3000 s/mm2) NODDI model using the AMICO toolbox. (c) The WM-VF, GM-VF, DEC were estimated by using the MRTrix3 toolbox. (d) The DTI tensor and FOD of the left centrum semiovale and the coronal radiata.
