Comparing High vs Standard Resolution PET Imaging in Prodromal Parkinson’s Disease
Official title: A Comparative Performance Study Between High and Standard Resolution Positron Emission Tomography (PET) Camera Using [18F]AV-133 in Prodromal Parkinson's Disease [Dual PET AV133 in Prodromal PD]
Run by Michael J. Fox Foundation for Parkinson's Research · NCT07809438 · Data updated 2026-11-12
We’re testing whether a high-resolution PET camera provides clearer images than a standard one for people in the prodromal phase of Parkinson’s disease.

Is this trial a fit for you?
✓Likely a good fit
Adults with prodromal Parkinson’s enrolled in the PPMI AV-133 sub study who can provide informed consent.
✕Probably not a fit
Participants who do not meet the eligibility criteria or cannot tolerate multiple scans may not benefit.

What this trial studies
This is a single-center, longitudinal imaging study at the Institute for Neurodegenerative Disorders in New Haven, CT. About 25 participants from the PPMI AV-133 prodromal imaging group will undergo a second PET scan using the NeuroEXPLORER camera after receiving [18F] AV-133, in addition to their standard PET scan. Scans occur at baseline, 1 year, and 2 years, with potential additional follow-ups. The study will also correlate imaging results with clinical, biomarker, and genetic data from the PPMI program.
Why it matters
Potential benefit: If successful, the study may show whether high-resolution PET imaging improves detection or measurement of prodromal Parkinson’s changes.
How similar studies have gone: Previous work in PET imaging for Parkinson’s prodromal stages has explored imaging approaches, with mixed results; this study contributes additional data on the NX camera’s performance.
