Fig. 6From: [18F]FEPPA PET imaging for monitoring CD68-positive microglia/macrophage neuroinflammation in nonhuman primatesSpearman’s correlation between [18F]FEPPA AI and CD68 immunoreactivity (CD68-ir) AI for each of the six monkeys (Spearman’s ρ = 0.94, p = 0.005). AI < 0 indicates increased [18F]FEPPA/CD68-ir in the ipsilateral putamenBack to article page
