CT scan may spare kids from invasive scope for inhaled objects
NCT ID NCT00747981
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This study tested whether a CT scan can accurately diagnose inhaled foreign bodies in children aged 6 months to 16 years, potentially avoiding the need for a more invasive endoscopy. Researchers compared CT scan results with endoscopy findings in 311 children suspected of having an object stuck in their lower airway. The goal was to see if the CT scan is reliable enough to guide treatment decisions safely.
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 CT scans prove reliable, many children could avoid the risks of an invasive endoscopy to check for inhaled objects.
- What could go wrong
- This is a completed diagnostic study, not a treatment trial. CT scans involve radiation, and the test may not catch all cases, so endoscopy might still be needed.
