New Radiation-Free lung scanner could transform monitoring of blood clot surgery

This study is testing whether a bedside imaging technique called electrical impedance tomography (EIT) can reliably measure blood flow in the lungs of patients with chronic blood clots. Thirty-six people scheduled for surgery to remove these clots will be monitored with EIT before and after the procedure. The goal is to see if EIT can provide useful information about lung blood flow without radiation or invasive procedures, potentially offering a safer way to track recovery.
