A Comparison of Technegas and Xenon-133 Planar Lung Imaging in Subjects Referred for Ventilation Scintigraphy

Summary

Phase 3 within-subject non-inferiority trial of Technegas ventilation imaging compared to Xenon-133 (Xe-133) ventilation imaging to demonstrate the non-inferiority of Technegas compared to Xe-133 ventilation studies with respect to subject pulmonary ventilatory distribution. Subjects will undergo site-specific standard of care (SOC) Xe-133 imaging per medical needs followed by Technegas ventilation imaging per study protocol.
