Comparing Electrical Impedance Tomography to Computed Tomographic Angiography

Active, Not Recruiting
View on ClinicalTrials.gov →
Summary
The study aim is to determine whether electrical impedance tomography (EIT) is equivalent in the detection of pulmomary emboli compared to Computed Tomographic Angiography (CTA). EIT is a non-invasive, non-ionizing functional imaging technique that can be performed at bedside. Electrical impedance tomography data will be collected on individuals undergoing a CTA scan of the chest at Medical Center of the Rockies (MCR). The primary outcome measure is to assess whether assessment by CTA corresponds with EIT in detection of pulmonary emboli. The study will include up to 63 participants. EIT data will be collected for up to 20 minutes during tidal breathing and for approximately five to ten seconds during breath-holding.
