Figure 1. Differences in longitudinal change in rCBF between APOE ε4 positive and ε4 negative groups.
Areas in blue show significantly greater longitudinal decreases in rCBF in the APOE ε4 carriers and those in green denote areas showing greater longitudinal decrease in rCBF in APOE ε4 non-carriers. The red line illustrates the z level of the representative slice shown.
