Associations of Pittsburgh compound‐B standard uptake value ratio adjusted for age and diffusion tensor imaging fractional anisotropy and mean diffusivity in white matter hyperintensities and normal appearing white matter. Regression lines and confidence limit bands show the relationship between DTI FA and predicted PiB SUVr with age adjustment representing a 75‐year‐old participant. The lowest FA value detected in the NAWM was 0.40. The highest MD value detected in the NAWM was 886 mm²/sec. FA, fractional anisotropy; MD, mean diffusivity; NAWM, normal appearing white matter; PiB, Pittsburgh compound‐B; SUVr, standard uptake value ratio; WMH, white matter hyperintensity.
