Background: The association between [F]Flortaucipir (FTP) and [F]MK6240, two commonly used tau-PET tracers in Alzheimer's disease (AD), varies due to distinct binding properties and off-target signal regions. Our study aims to elucidate the biological factors influencing this association and evaluate the applicability of a common equation across different on-target regions.
Method: 113 individuals from the HEAD dataset (11 young, 58 cognitively unimpaired elderly, and 44 cognitively impaired) underwent [F]MK6240, [F]FTP and Aβ-PET scans.
Background: Differences between on- and off-target retention characteristics between [F]MK6240 and [F]Flortaucipir (FTP) complicate the harmonization across tracers. Our objective here was to separate the impact of the reference region by evaluating correlations between [F]MK6240 (MK) and [F]FTP standard uptake values (SUVs).
Method: Participants (Figure 1, n=90) received an amyloid-β (Aβ) PET scan ([C]PIB or [F]NAV4694) and two tau-PET scans: [F]MK (90-110 minutes post-injection) and [F]FTP (80-100 minutes post-injection).

Background: Tau-PET tracers have been used to diagnose and stage Alzheimer's disease. However, different tau tracers present distinct patterns of binding throughout the brain, challenging the harmonization of their results. We hypothesize that the choice of a reference region can impact the harmonization of the tau-PET standardized uptake value ratio (SUVR).

Compared to other appointment methods in public hospitals, registering through the Internet or utilizing e-appointments, or registering online as an outpatient, can provide more information to the user. This research investigated the integration of unified theory of the acceptance and use of technology and information system quality in determining factors that influence the adoption of e-appointments by patients, based on the requirements of food safety consultation in Taiwan. Empirical data from 369 valid samples were assessed using Partial Least Squares (PLS).
