Table 1.

The results (mean±SD) of the diffusion tensor of 4kDa FTIC-Dextran in the five regions of porcine TMJ discs. D_{Eig_Min} and D_{Eig_Max} are the two principal diffusivities of the diffusion tensor. (D_{Eig_Min} + D_{Eig_Max})/2 is the characteristic diffusivity that represents the averaged solute diffusion rate in each disc region. D_{Eig_Min}/D_{Eig_Max} was calculated to evaluate the anisotropy of solute diffusion in each disc region.
