Diffusivity is a rate of diffusion, a measure of the rate at which particles or heat or fluids can spread. It is measured differently for different mediums. Diffusivity may refer to: • Thermal diffusivity, diffusivity of heat WebJan 25, 2008 · look at the “axial diffusivity,” i.e., the principal eigenvalue of the DT, and at the “radial diffusivity,” i.e., the average of the second and third eigenvalues of the DT, in an animal model, and where they link the radial diffusivity with myelin content, studies reporting comparisons of these indices are becoming very frequent (e.g ...
