Given that some cortical regions in DLB and/or AD could be characterized by changes in regional cerebral blood flow (Colloby et al. 2013) and the diffusion indices could be biased by different location and volume of thalamic connectivity-defined regions determined by the tracking algorithm, we adopted 3 different strategies.
The microarchitecture of subchondral trabecular bone in joints has a significant dependence on aging, which is characterized by a decrease in trabecular thickness and bone volume fraction, loss of connectivity, increased trabecular separation and bone marrow space volume, transformation of trabeculae from plate-like into rod-like, and an increase in anisotropy degree [ 48].
Avizo 6.3 [22] was used for analyzing these volumes in terms of connectivity and morphology.
MR images and relaxation measurements revealed a marked increase in the volume and connectivity of pre-existing pore networks in the carbonate core.
The relationships between fractal dimension and permeability in type I and II are different, which may be related to volume and connectivity of mesopores and macropores.
We discuss several arguments which lead us to a number of results and bounds of quasi-isometric distortion: comparison of volumes, connectivity, etc.
Results highlight strong dependencies of pore volume, pore connectivity, throat geometry and fluid conductance on the degree of tetrahedra merging and the specific characteristics of the throats targeted by the merging algorithm.
The tests applied in this study consisted of computing correlation coefficients between the temporal expression coefficients and the modelled hemodynamic response of the paradigm to establish task relationship (ecc) and between component image volumes to determine topographical similarity of connectivity patterns (rcc).
In addition to volume changes, connectivity changes of axonal fiber bundles have been investigated using diffusion tensor imaging (DTI).
In this paper, we apply a special finite-volume scheme, limited to smooth temperature distributions and Cartesian grids, to test the importance of connectivity of the finite volumes.
