Radiation-Free lung imaging could replace CT scans?
NCT ID NCT07756086
First seen Aug 10, 2026 · Last updated Aug 11, 2026 · Updated 1 time
Summary
This study tests whether a noninvasive, radiation-free imaging method called 3D electrical impedance tomography (3D-EIT) can accurately measure how air distributes in the lungs during breathing. Researchers will compare it to 4D computed tomography (4D-CT), which provides detailed images but uses radiation. About 50 adults, including healthy volunteers and ICU patients, will undergo both scans simultaneously. If 3D-EIT matches CT's accuracy, it could offer a safer, continuous way to monitor lung ventilation in the future.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Three-Dimensional Electrical Impedance Tomography (3D-EIT) device
- What this could lead to
- If 3D-EIT proves accurate, it could become a noninvasive, radiation-free way to monitor lung ventilation in real time, especially for critically ill patients.
- What could go wrong
- This is a small observational study, and 3D-EIT may not match CT's precision. Its results are for research only and won't guide treatment decisions yet.
