What this trial is about
The goal of this clinical trial is to evaluate the efficacy and safety of XTR006 injection PET visual reading in detecting brain neurofibrillary tangles (NFTs) in elderly subjects with Mild Cognitive Impairment (MCI), Alzheimer's Disease (AD), and cognitively normal individuals. The main question it aims to answer is: • What is the sensitivity and specificity of XTR006 PET visual reading results compared to the truth standard across MCI, AD, and cognitively normal subjects? Participants will: * Receive XTR006 injection * Undergo PET/CT scanning
