Can a simple electrical scan spot dangerous lung clots without radiation?
NCT ID NCT07724197
First seen Jul 24, 2026 · Last updated Jul 24, 2026
Summary
This study is testing whether a noninvasive imaging technique called pulsatile electrical impedance tomography (EIT) can accurately diagnose acute pulmonary embolism — a life-threatening blood clot in the lungs. Researchers will compare EIT readings with standard CT scans in 275 adults to see if EIT can identify clots, assess their severity, and track changes over time. If successful, EIT could provide a safe, bedside alternative to radiation-based imaging.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- pulsatile electrical impedance tomography (EIT) — a noninvasive, radiation-free imaging technique that measures how electrical currents move through the lungs to detect blood flow problems
- What this could lead to
- If EIT proves accurate, it could offer a quick, bedside, radiation-free way to diagnose pulmonary embolism, replacing or reducing the need for CT scans.
- What could go wrong
- This is an early diagnostic study, not a treatment trial. EIT may not be sensitive or specific enough to replace standard CT angiography, and results may vary across different patient groups.
