Simple global measures describing the complexity of the white matter architecture can provide useful information when analyzing diffusion MRI data, and can be even capable of finding statistical differences between groups. We propose the use of the fractal dimension of the FA maps for that purpose, and illustrate its potential on a dataset composed of elderly subjects and patients from three different stages of Alzheimer’s disease.
