Status: Enrolling

ClinicalTrials.gov Number: NCT03054870

Phone: 956.543.5198

Protocol Number: Pro00019288


The purpose of this research study is to see how safe and effective the use of Technegas imaging is in lung imaging. Technegas is an investigational aerosol imaging agent that you inhale that makes the lungs show up during a nuclear medicine ventilation imaging scan. A ventilation imaging scan is a type of nuclear medicine imaging test, which means it uses a radioactive drug and a special camera to create pictures of your lungs. Images of the lungs will be taken using the approved Xenon-133 gas followed by the same pictures using the Technegas study drug. The images will be used to see how well the study drug (Technegas) works to take images of the lungs compared to the approved drug Xenon. Approximately 240 subjects from approximately 10 sites in the U.S. are planned for enrollment in the study
