Fig. 4 From:Quantitative analysis of macroscopic solute transport in the murine brain Simplified illustration of a DCE-MRI voxel, which measures 60 μm on a side, in the brain tissue subdomain (light blue in Fig.3A). Each voxel in the brain tissue subdomain contains interstitial space and PVSs too small to resolve by MRI. Therefore, the transport parameter determined for this subdomain combines transport in the interstitial space and PVSs Back to article page
