Fig. 1From: Measuring cortical mean diffusivity to assess early microstructural cortical change in presymptomatic familial Alzheimer’s diseaseCortical parcellation and measurement of cortical MD. Each T1 image (a) underwent cortical parcellation using FreeSurfer (v5.30) (b). The FreeSurfer label for each ROI was warped into diffusion space (c) and registered to the MD map (d) to allow extraction of mean MD within that region (e)Back to article page
