Regional Fluid-Attenuated Inversion Recovery (FLAIR) at 7 Tesla correlates with amyloid beta in hippocampus and brainstem of cognitively normal elderly subjects.

For 10 out of 29 brain regions a nominally significant relationship could be observed: Right Hippocampus (rho = 0.86, −log(p) = 3.84), Brainstem (rho = 0.85, −log(p) = 3.56), left Hippocampus (rho = 0.84, −log(p) = 3.41), left Basal Ganglia vessels (rho = 0.82, −log(p)= 2.90), left Choroid Plexus (rho = 0.73, −log(p) = 2.05), right Basal Ganglia vessels (rho = 0.69, −log(p) = 1.86), right ventral Diencephalon (rho = 0.65, −log(p) = 1.56), right Caudate (rho = 0.64, −log(p) = 1.56), right Accumbens area (rho = 0.61, −log(p) = 1.41), and right Amygdala (rho = 0.60, −log(p) = 1.32) (Table 2 and Figure 3A ).
