Summary

This study is testing whether a CT-free electromagnetic navigation system can accurately locate small lung nodules before surgery, compared to the standard CT-guided method. The goal is to see if the new approach can mark nodules within 10 millimeters of their center, which is crucial for successful removal. Researchers will also compare procedure time, complications, and recovery. The study involves adults with non-palpable pulmonary nodules who need sublobar resection.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: CT-Free electromagnetic navigation percutaneous localization system
What this could lead to: If successful, this could offer a safer, faster, and more accurate way to mark lung nodules before surgery, potentially reducing the need for repeated CT scans and improving surgical outcomes.
What could go wrong: This is an observational study, so it cannot prove cause and effect. The new method may not be as accurate or safe as standard CT-guided localization, and results may vary across different centers.
