TECHNEGAS KIT (technetium tc-99m labeled carbon)

Cardiovascular Approved 2023-09-29

Technegas is an inhalation aerosol used for adults and children aged six years and older to help visualize how air flows through the lungs. It helps clinicians evaluate patients for potential pulmonary embolisms when used alongside perfusion imaging. This diagnostic tool provides a way to see pulmonary ventilation to assist in respiratory assessments.

How TECHNEGAS KIT Works

This aerosol works by depositing radioactive carbon particles onto the lining of the small airways and air sacs within the lungs. The distribution of these particles is driven by the lungs' natural airflow rather than specific chemical receptors. This allows the system to create a map of where air is reaching in the pulmonary system.
