Fig. 2From: The relationships between neuroinflammation, beta-amyloid and tau deposition in Alzheimer’s disease: a longitudinal PET studyAmyloid and inflammation correlations in the low PiB group. Regions where uptake of PiB and PK are positively correlated in the low PiB group at baseline and after 2 years. a Across the 15 low PiB MCI subjects. b Baseline and follow-up correlation for the 7 low PiB subjects who showed increasing PiB signal over 2 years—three crossing the 1.5 threshold. c Baseline and follow-up correlation for 8 cases in the low PiB subgroup who showed no increase in PiB uptake over 2 years (P < 0.05; cluster FWE rate, P < 0.05)Back to article page
