Xenon gas MRI: a safer way to see inside lungs and brain?
NCT ID NCT02195206
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This pilot study tested a new MRI technique that uses inhaled xenon gas instead of X-rays to create images of the lungs and brain. Forty healthy adults aged 18 to 75 took part. The goal was to see if this method produces clear images without radiation. The study was terminated early, so results are limited.
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-129 gas
- What this could lead to
- If successful, this could lead to a safer, radiation-free imaging method for lungs and brain, potentially improving diagnosis of lung diseases.
- What could go wrong
- This is a very early pilot study with only 40 healthy volunteers. It was terminated, so results may be limited. The technique may not work as well in patients or in larger studies.
