Using multi-excitation MRE and TI-NLI, we estimated and found
significant differences in the anisotropic mechanical properties, substrate
shear modulus μ, shear anisotropy φ, and tensile
anisotropy ζ, within individual
regions of interest of the human brain.
Figure 3: Representative slice for each subject
investigated showing each of the three anisotropic material parameters: μ, φ, and ζ.
Figure 4: Representation of the three anisotropic
material parameters (μ, φ, ζ) in WM tracts: corpus
callosum (CC), corona radiata (CR), and superior longitudinal fasciculus (SLF).
