Figure 2. Associations Between Baseline FBP SUVR and Follow-up FTP SUVR in Precentral and Postcentral Cortical Regions.

The comparisons of Aβ-related higher tau levels between OA+ and OA− groups in (A) precentral and (B) postcentral regions. Aβ = β-amyloid; FBP = ¹⁸F-florbetapir; FTP = ¹⁸F-flortaucipir; OA+ = participants with osteoarthritis; OA− = participants without osteoarthritis; SUVR = standard uptake value ratio.
