Fig. 2From: Partial volume correction for arterial spin labeling using the inherent perfusion information of multiple measurementsROI analysis for GM CBF under different noise levels. Each data point represents the mean GM CBF for all voxels falling within a 10 percentile range of the GM probability. From top to bottom: different levels of Gaussian noise, with a standard deviation of 5, 10 and 15, respectivelyBack to article page
