Cerebral Blood Flow Measurement Using fMRI and PET: A Cross-Validation Study
Figure 3
Sample ROIs (shown in red) defined for one
subject. The V1 ROI was obtained by retinotopic mapping, the t-map ROI included common voxels from
thresholded and resampled FAIR and PET t-maps,
and the grey matter (GM) ROI was defined by Bayesian classification of the
anatomical structures.
