VGAS, total lung gas volume; VHYP, hyperinflated lung volume; VNON, non-aereated lung volume; VNORM, normally aereated lung volume; VPOOR, poorly aerated lung volume; VTISS, total lung tissue volume; VTOT, total lung volume.
Histomorphometric examination of the femur supported these density measurements, with bone volume per total volume increasing by 32% (p = 0.04).
Vessel density (vessel volume per tissue volume, VV/TV) was computed in analogy to bone volume per tissue volume (BV/TV).
BV/TV indicates the percentage of bone volume in the total tissue volume and is an indicator of changes in total bone volume.
BV/TV indicates the proportion of bone volume in the total tissue volume and is an indicator of changes in the total bone volume.
Parameters like fractional bone volume (bone volume per tissue volume, BV/TV), trabecular number (Tb.N), trabecular thickness (Tb.Th).
Total brain volume (an indicator of atrophy) was derived as the percentage of the total tissue volume to the intracranial volume.
The abluminal endothelial cell surface area (ECSA) was taken as 1000 µm2 per endothelial cell, averaged from hamster arteriolar [77] and dog aortic endothelial cells [78]; while the total abluminal endothelial surface area per tissue volume (ESAV) available for ligand-receptor binding came to 44 cm2/cm3 tissue.
The total tissue volume (TV, mm) is the volume of the whole examined sample.
In conclusion, the VEGF molecules can diffuse in the available interstitial fluid volume U AV = K AV × U. Similarly, the free VEGF concentration in the available interstitial fluid volume, noted [ V] AV, is related to the free VEGF concentration in the total tissue volume [ V] by [ V ] A V = [ V ] K A V. Until now, all the equations have been expressed per unit volume of total tissue.
