fluorine F 18-FEQA
(FLOOR-een …)
A radioactive substance being studied in positron emission tomography (PET) imaging to diagnose cancer and to find out how well some types of cancer respond to treatment. Fluorine F 18-FEQA binds to the epidermal growth factor receptor (EGFR), which is found on some cancer cells. The PET scan forms an image that shows where cancer cells with EGFR can be found in the body.
