From: Fibre density and cross-section associate with hallmark pathology in early Alzheimer’s disease
Longitudinal whole-brain fixel-based analysis. (A) Decreased fibre density, (B) fibre cross-section and (C) fibre density and cross-section in aMCI patients at follow-up compared to baseline. Results are shown as streamline segments traversing fixels (PFWE<0.05) and coloured by diffusion direction: red = right-left; green = anterior-posterior; blue = inferior-superior. Images are shown in radiological convention. aMCI = amnestic mild cognitive impairment
