Figure 14.
Axial slices through the cases corresponding to a male 66-year-old control and a male 78-year-old with MCI. (a) Principal eigenvalue of the permeability tensor, (b) clearance and (c) CSF/ISF accumulation (ζe). The two latter sets of results depict the influence of incorporating anisotropic permeability (which is influenced by the local microstructure). Black arrows indicate the regions with peak drainage for the respective cases. (d) An axial slice of the MCI case depicting the clearance (CLR) of CSF/ISF (in the form of filtration velocity vectors) superimposed with the ICP solution field. (e) A coronal slice of the MCI case depicting clearance (CLR) of CSF/ISF superimposed with the ICP solution field. (Online version in colour.)
