(Ã¢ÂÂ¦-FLOOR-oh-MY-soh-NID-uh-sole) A radioactive substance being studied as an imaging agent in head and neck cancers and other types of cancer. It binds to large molecules in tumor cells that have a low level of oxygen. Radiation given off by 18F-fluoromisonidazole is detected by a PET scan. The amount of 18F-fluoromisonidazole in the tumor may help decide the best treatment and help predict whether the cancer will come back after treatment. 18F-fluoromisonidazole is a type of radioimaging agent. Also called 18F-MISO and FMISO.
