Figure 3

Relationship and Bland-Altman plot for Group-1 between the emission- and transmission-based methods. The regression lines are y = 0.88 x + 0.05 ml/min/g (r = 0.92), y = 0.97 x + 0.01 ml/min/g (r = 0.97), and y = 0.88 x + 0.003 ml/min/g (r = 0.89), 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 −0.000 ± 0.047 ml/min/g for CBF, 0.001 ± 0.012 for OEF, and −0.0005 ± 0.0043 ml/min/g for CMRO2, respectively.
