New imaging agent may reveal hidden lung scars in COVID survivors
NCT ID NCT04376593
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early-phase study tested a radioactive tracer called 18F-αvβ6-BP in 5 people who had recovered from COVID-19. The goal was to see if the tracer could highlight lung damage on PET/CT scans. Participants received the tracer intravenously and underwent imaging. The study only assessed whether the tracer could be given safely and whether it accumulated in areas of lung injury.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
18F-αvβ6-binding-peptide (a radioactive tracer for PET scans)
What this could lead to
If successful, this imaging method could help doctors see lung damage from COVID-19 more clearly, potentially guiding treatment decisions.
What could go wrong
This is a very early, tiny study (5 people) that only tests whether the tracer can be given safely and shows up in the lungs. It does not test any treatment or long-term outcomes.
