<b>BACKGROUND AND PURPOSE:</b> Cerebral blood volume (CBV) is an important parameter in estimating the viability of brain tissue following ischemic event. We tested hypothesis that C-arm CT measurements CBV would correlate well with those made perfusion (PCT). <b>MATERIALS METHODS:</b> was measured 12 canines by using PCT and CT. Two each technique were on animal; a different injection protocol used for these techniques. performed 64-section V-scanner. biplane Artis dBA system. images transferred to commercially available workstation postprocessing analysis; analysis prototype software. From animal, 2 sections from selected analysis. <b>RESULTS:</b> There good agreement both color maps absolute numbers between The maximum mean deviations values techniques first 5 animals 30.20% 7.82%; second 7 animals, 26.79% 7.40%. studies 33.15% 12.24%; 41.15% 10.89%. <b>CONCLUSIONS:</b> In healthy measurement compared PCT.
