The values for OEF, CBF, and CMRO₂ are expressed as local-to-global ratios (see Methods). For the 19 subjects in group II the global values for OEF and CBF (± SD) were 0.30 ± 0.09 (dimensionless) and 48 ± 10 ml/(min × 100 g), respectively. The mean arterial oxygen content for this group was 17.0 ± 0.02 ml/ml. From these data quantitative images of the CMRO₂ were created that yielded a mean cerebral hemisphere value of 2.17 ± 0.41 ml/(min × 100 g) or 0.97 ± 0.17 μmol/(min × g). The asterisks denote values that differ significantly from the global mean after correction for multiple comparisons.
