Tiny study checks if new brain scanner tracer works reliably
NCT ID NCT03649555
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tested how reliably a new radioactive tracer, [18F]-FTC-146, shows up in brain scans of healthy people. Five volunteers received the tracer on two separate days to see if the results were consistent. The goal was to understand the tracer's stability, not to treat any condition.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
[18F]-FTC-146 (a radioactive tracer for brain imaging)
What this could lead to
If successful, this could help develop a reliable way to measure sigma-1 receptors in the brain, which may aid future research into neurological conditions.
What could go wrong
This is a very early, small study with only 5 healthy participants. It is designed to test reliability, not to treat any disease, so it may not lead to any direct medical benefit.
