Fluoroestradiol F-18

Fluoroestradiol F-18 is an imaging agent used with positron emission tomography (PET) to detect estrogen receptor-positive breast cancer lesions. The ability to image ER-positive tumors in vivo is advantageous in that, while helping to visualize tumor progression/regression, it may also be used to assess for heterogeneity in ER expression across metastases (i.e. to identify sites that no longer express ER) without the need for multiple biopsies. Fluoroestradiol F-18 was first granted FDA approval in May 2020, and will be developed by PETNET Solutions, Inc. and Zionexa USA under the brand name Cerianna. It is expected to be available in late 2020/early 2021.

Fluoroestradiol F-18 is a radioactive diagnostic agent indicated for use with positron emission tomography (PET) imaging for the detection of estrogen receptor-positive lesions as an adjunct to biopsy in patients with recurrent or metastatic breast cancer.
