Scans reveal hidden damage in COVID Long-Haulers
NCT ID NCT05920616
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This completed study used advanced MRI and CT scans to look for lasting damage in the brain, heart, lungs, and liver of 206 people who had COVID-19. Researchers compared those who were hospitalized with those who were not, to understand how the virus affects organs over time. The goal is to help prevent, detect, and manage long-term complications from COVID-19.
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 study could help doctors better detect and manage long-term organ damage from COVID-19.
- What could go wrong
- This is an observational study, not a treatment trial. It cannot prove that any intervention works, and results may not apply to all COVID-19 survivors.
