Technetium Tc 99m-demobesin-4
Pronunciation
A substance being studied as a way to find certain types of cancer. It contains a radioactive substance called technetium linked to another substance called demobesin. Demobesin binds to the receptor for bombesin (a substance that is found at higher-than-normal levels on some types of cancer cells). Technetium Tc 99m-demobsin-4 collects in cancer cells and a machine is used to find where the cancer cells are in the body. It is a type of radiopharmaceutical and a type of radioimaging agent.
