Correlation (a, c and e) and Bland-Altman plots (b, d and f) of PET-MR-based regional MBF std (clinical protocol) versus PET-CT-based regional MBF at rest (a, b), regional MBF at rest corrected for RPP (c, d) and at regional MBF at adenosine-stress (e, f). The solid lines in a, c and e are lines of identity. The solid lines in b, d and f indicate the mean difference (bias), whereas the dashed lines show the limits of agreement. Regression slopes are 2.12 (1.26–2.99), 0.92 (0.72–1.11) and 0.85 (0.73–0.97) in a, c and e, respectively. Bias (limits of agreement) are −0.008 (−0.34 to 0.33), −0.03 (−0.29 to 0.23) and −0.07 (−0.99 to 0.85) in b, d and f, respectively
