New MRI gas test could spare kids from risky lung procedures
NCT ID NCT07545304
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a special MRI scan that uses xenon gas to find blockages in the lungs of children with protracted bacterial bronchitis (PBB), a condition causing a long-lasting wet cough. Current diagnosis often requires a bronchoscopy (camera in lungs under anesthesia) or a CT scan (which uses radiation). The MRI is safer and radiation-free. Researchers will compare the MRI results from 30 children with PBB to data from healthy children to see if this method can reliably detect lung problems.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- xenon gas
- What this could lead to
- If successful, this MRI method could replace risky procedures like bronchoscopy and CT scans, making diagnosis easier and safer for children.
- What could go wrong
- This is a small, early study with only 30 children. The MRI technique may not be accurate enough to replace current methods, and results may not apply to all children.
