Arterial Spin Labeling (ASL) fMRI: Advantages, Theoretical Constrains and Experimental Challenges in Neurosciences

Figure 4

Voxelwise estimation of ATT values using a multiple-labeling-duration acquisition described in Borogovac et al. [55]. The units in the color bars are in seconds. Note regional heterogeneity in group mean ATT shown in the 2nd row. Also, across subjects standard deviation maps (3rd row) indicate variability in ATT especially in the posterior regions. This variability is expected to be higher in disease. Figure taken with permission from Borogovac et al. [55].
