Figure 4

Relationship and Bland-Altman plot for Group-2 between the emission- and transmission-based methods. The regression lines are y = 0.91 x + 0.02 ml/min/g (r = 0.96), y = 0.97 x + 0.01 ml/min/g (r = 0.99), and y = 0.84 x + 0.003 ml/min/g (r = 0.90), 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 −0.014 ± 0.048 ml/min/g for CBF, −0.003 ± 0.013 for OEF, and −0.0015 ± 0.0048 ml/min/g for CMRO2, respectively.
