NCT ID NCT04659707
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This completed study looked at lung function in 42 people recovering from COVID-19. Participants inhaled a special form of xenon gas that shows up on MRI scans, allowing researchers to see how well different parts of the lungs were working. The goal was to understand how mild, moderate, and severe COVID-19 affect lung structure and function over six months.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Hyperpolarized xenon gas (inhaled for MRI imaging)
What this could lead to
If successful, this could help doctors better understand how COVID-19 affects the lungs over time and guide recovery monitoring.
What could go wrong
This is a small, early-phase study with only 42 participants, so results may not apply to everyone. It is designed to observe, not treat, the disease.
