Summary
The goal of this clinical trial is to evaluate an investigational ultralow dose PET imaging technique for Alzheimer's disease, mild cognitive impairment, other forms of dementia detection and monitoring. The main question it aims to answer is: Can the investigators optimize the timing, scan duration, and image reconstruction to reduce the radiation dose 10-100 fold of the current clinical standard? Participants will be injected with a radioactive tracer called 18F-Florbetapir or 18F-Flutemetamol and be imaged on a new type of high-sensitivity PET scanner for up to 3 hours
Eligibility
Inclusion Criteria5
- Age ≥18 years.
- Ability to provide informed consent and comply with study procedures.
- For female participants:
- Must not be pregnant or breastfeeding.
- Negative pregnancy test required for women of childbearing potential.
Exclusion Criteria6
- Participants who have exceeded NRC regulation for annual radiation exposure from prior research-related scans, including this study (50 mSv total).
- More than four prior enrollments in this study.
- Participants with severe claustrophobia, chronic pain, or musculoskeletal conditions that prevent completion of the PET scan
- Pregnant or breastfeeding individuals (negative pregnancy test required)
- Inability to provide informed consent
- Any condition that, in the investigator's judgment, may compromise participant safety or study integrity.
