MAPT and Alzheimer disease: The pattern of brain [18F]MK-6240 uptake distribution was consistentwith previous studies (Betthauser, Cody, et al.,2019;Fu et al., 2023;Guehl et al., 2019;Pascoal et al., 2018) and with the expectedlocalization of tau across the AD spectrum (Braak & Braak, 1999;Kreislet al., 2022;Pascoal et al.,2020a), and was similar in the Test and Retest scans (Supplementary Fig.1).
