Deep learning noise reduction for amyloid PET imaging in Alzheimer’s patients
Official title: Impact of Deep Learning-Based Noise Reduction Algorithm on Visual Analysis and Centiloid Quantification in Reduced-Dose and, or Time Acquisition Amyloid PET Imaging
Run by Central Hospital, Nancy, France · NCT07309107 · Data updated 2026-11-12
Researchers are testing a deep learning noise-reduction method to see if it lets doctors use lower radiation doses or shorter scan times for amyloid PET imaging in people with cognitive impairment.

Is this trial a fit for you?
✓Likely a good fit
Patients with objective cognitive impairment referred for an 18F-flutemetamol PET scan at CHRU Nancy between Jan 1, 2023 and Jul 1, 2025.
✕Probably not a fit
Patients for whom deep learning imaging becomes unreliable or those who refuse data usage.

What this trial studies
This observational study looks at how a deep learning–based noise reduction algorithm affects visual interpretation and Centiloid measurements when simulating reduced injected doses of 18F-flutemetamol. The goal is to determine whether image quality and quantitative results remain reliable with less data. Data will come from patients referred for an amyloid PET scan at CHRU Nancy between 2023 and 2025. No interventions are being tested beyond the imaging processing method, and participation is limited to use of patients’ data with consent.
Why it matters
Potential benefit: If successful, patients could benefit from lower radiation exposure and shorter scan times without sacrificing diagnostic accuracy.
How similar studies have gone: Previous work in PET imaging with deep learning noise reduction has shown promise, but results can vary by protocol and tracer; this study adds specific assessment for amyloid imaging with flutemetamol.
