[18F]-APN-1607
What this trial is about
1. To evaluate the diagnostic performance of \[18F\]-APN-1607 injection PET imaging in detecting uptake patterns consistent with AD neuropathological changes as defined by the National Institute on Aging-Alzheimer's Association (NIA-AA) criteria. 2. To assess the association between \[18F\]-APN-1607 injection and Alzheimer's disease (AD)-related tau neurofibrillary pathology (as determined by post-mortem brain tissue histopathology), and detect the uptake pattern corresponding to neurofibrillary tangle (NFT) scores. 3. To evaluate the safety of \[18F\]-APN-1607 injection.
