Fig. 7From: A semi-automated measuring system of brain diffusion and perfusion magnetic resonance imaging abnormalities in patients with multiple sclerosis based on the integration of coregistration and tissue segmentation proceduresAn illustrative example of normal appearing tissue segmentation. T1 = 2D axial non-enhanced T1-weighted spin-Echo or 3D non-enhanced T1-weighted gradient-Echo MRI images; FSL = FMRIB Software Library; FIRST = FMRIB’s Integrated Registration and Segmentation Tool; SIENAX = Structural Image Evaluation using Normalization of Atrophy; r_T1 = registered 2D axial non-enhanced T1-weighted spin-Echo or 3D non-enhanced T1-weighted gradient-Echo MRI images; NAGM = normal appearing grey matter; NAWM = normal appearing white matterBack to article page
