IC‐O1–05: APOE‐ε4 is associated with increased hippocampal atrophy rates in Alzheimer's disease

tion (PIB-PET) in ApoE4+ AD and ApoE4AD subjects. A) Differences in ApoE groups compared with controls. Maps show t-values corrected for multiple comparisons (FWE p<0.05). B) Direct comparison between ApoE AD groups. Shown are statistical t-maps at uncorrected threshold of p<0.01 for FDG, and FWE-corrected (p<0.05) for PIB ApoE4> ApoE4+, and uncorrected at p<0.05 for ApoE4+ > ApoE4-. Shown are also percent difference maps (-10% to 10%) to provide a fuller characterization of the FDG and PIB patterns, with red indicating higher FDG/PIB uptake in the ApoE4-patients compared with ApoE4+, and blue indicating the reverse contrast.
