Fractional anisotropy and mean diffusivity: comparison between
WebJan 4, 2024 · The most common metrics of diffusion tensor imaging used are fractional anisotropy (FA) and mean diffusivity (MD) [ 10, 11, 12, 13, 14, 15 ]. DTI facilitates the reconstruction and investigation of the language areas and allows anatomical assessment of damage-dysfunction relationships [ 16, 17, 18 ]. WebFeb 25, 2024 · Finally, the mean general fractional anisotropy (GFA), quantitative anisotropy (QA), normalized quantitative anisotropy (NQA), and isotropic diffusion component (ISO) values were calculated, as well as the elementary DTI parameters including fractional anisotropy (FA), mean diffusivity (MD), axial diffusivity (AD), and radial diffusivity (RD).
