WebApr 10, 2024 · DTI-based assessment of white matter microstructure has four different parameters: fractional anisotropy (FA), mean diffusivity (MD), axonal diffusivity (AD), and radial diffusivity (RD). FA is the total magnitude of water directional movement along the axonal fiber, and a sensitive indicator of changes in white matter structure. WebDiffusion tensor imaging or “DTI” refers to images describing diffusion with a tensor model. DTI is derived from preprocessed diffusion weighted imaging (DWI) data. First proposed …
