Can a brain scan reveal the hidden amyloid behind neurodegenerative disease?
NCT ID NCT06725706
First seen Sep 08, 2026 · Last updated Sep 09, 2026 · Updated 1 time
Summary
This study tests whether PET/CT scans using two radioactive tracers, 18F-92/AV45 and 11C-PIB, can detect beta amyloid buildup in the brain. Researchers will enroll 500 adults with suspected or known neurodegenerative diseases linked to amyloid. Each participant receives one injection of the tracer and undergoes imaging. The goal is to see if these scans can accurately diagnose amyloid-related conditions and measure how much amyloid is present.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- 18F-92/AV45 and 11C-PIB, radioactive tracers used in PET/CT imaging to detect beta amyloid in the brain
- What this could lead to
- If these scans prove accurate, doctors may have a reliable way to spot amyloid-related brain diseases earlier and distinguish them from other conditions.
- What could go wrong
- The study is still in early stages, and the scans may not clearly separate different neurodegenerative diseases. There is also a small risk from radiation exposure during imaging.
