Cortical fractal dimension predicts disability worsening in Multiple Sclerosis patients

open access: yesNeuroImage: Clinical, 2021
Background: Fractal geometry measures the morphology of the brain and detects CNS damage. We aimed to assess the longitudinal changes on brain’s fractal geometry and its predictive value for disease worsening in patients with Multiple Sclerosis (MS ...
