Quantifying Cerebellum Grey Matter and White Matter Perfusion Using Pulsed Arterial Spin Labeling
Figure 8
Analysis results for evaluating susceptibility and partial volume effects on cerebellar CBF measurements: (a) scatter plots of CBF versus voxel intensity for cerebellar grey matter (left) and white matter (right) from one typical subject show no relation between these two parameters; (b) grey matter voxels with intensity <800 were located almost entirely at the superficial cerebellar boundaries, as shown by images with (left) and without (right) anatomic underlays; (c) histogram distribution plots of cerebellar grey matter and white matter signal intensities from one typical subject showing high-intensity tail for WM and low-intensity tail for GM.
