NCT ID NCT04841707
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study used advanced total-body PET scans to look at how COVID-19 affects the lungs' blood-air barrier. Thirteen adults who had COVID-19 and healthy volunteers each had two scans, one at the start and one four months later. The goal was to measure changes in lung function over time and compare them to normal lungs.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
What this could lead to
If successful, this could help doctors better understand how COVID-19 damages the lungs and guide future treatments.
What could go wrong
This is a very small, early study with only 13 people, so results may not apply to everyone. It is designed to observe, not to test a treatment.
