Description

Fluoroestradiol F-18 is a derivative of estradiol. where hydrogen at position 16 is replaced by radioactive fluorine. Fluoroestradiol F-18 is taken up by tumor cells, expression estrogen receptor, and it is clinically evaluated for PET imaging to detect and stage breast cancer, ovarian cancer, and cancer of uterine endometrium and myometrium.
