Relationship and Bland-Altman plot for Group-0 between the emission- and transmission-based methods. The regression lines are y = 0.83 x + 0.05 ml/min/g (r = 0.92), y = 0.91 x + 0.04 ml/min/g (r = 0.96), and y = 0.79 x + 0.005 ml/min/g (r = 0.92), for CBF, OEF, and CMRO₂, respectively. In the Bland-Altman plot, solid and broken lines show mean of difference and its respective 2SD, respectively. Mean ± SD values are −0.013 ± 0.047 ml/min/g for CBF, 0.001 ± 0.018 for OEF, and 0.0014 ± 0.0042 ml/min/g for CMRO₂, respectively.
