Figure 2. Calculating CVR values from fMRI data in 32 healthy individuals. Comparing two different analysis approaches (fMRI: linear regressionvs. TCD: 30-s steady state) applied to fMRI data acquired in two different experimental conditions (stimulus concentration: 5% vs. 7% CO2). Pearson’s correlations revealed significant association of CVRs derived from each analysis approach for both 5% CO2 (r 1⁄4 0.872; p < 0.001) and 7% CO2 (r 1⁄4 0.956; p < 0.001). Claire V.
