Figure 2

Relationship of CO 2 -reactivity with PET values. Scatter plots showing the relationships of CO2-reactivity with CBF (upper panel), OEF (middle panel), and CBV/CBF (lower panel). Within each panel, absolute values are shown on the left and ipsilateral/contralateral ratios on the right. The grey dots in the panels on the right indicate the three outliers.
