Figure 2

Bland-Altman plot of the difference between rCBF CT and rCBF PET against their mean values. The middle line indicates the mean difference. The outer lines indicate 95% limits of agreement. The rCBF CT values are biased and are all larger than the rCBF PET values, and the difference increases with increasing mean rCBF values. Cross mark, grey matter; empty circle, white matter.
