Technegas™ is an ultra-fine dispersion of Technetium-labelled carbon, produced by heating Technetium-99m in a carbon crucible for a few seconds at 2,750 degrees Celsius1. The resultant gas-like Technegas™, thus produced in a Technegas generator, is a dispersion of nanosized (average size 30-60nm) pure carbon platelets of hexagonal shape fully encapsulating Technetium metal crystals2. The small size and hydrophobic properties together confirm ideal characteristics for gas-like behaviour and alveoli deposition into the lungs2-3. Technegas™ penetrates to the sub-segmental areas of the lung and is trapped by surfactant in the alveolar walls4.
