Uses for Cerianna
Fluoroestradiol F 18 injection is used together with biopsy to help detect estrogen receptor (ER)-positive lesions in patients with recurrent or metastatic breast cancer (cancer that keeps coming back or has spread to the other parts of the body). It is used in a procedure called positron emission tomography (PET) scan to help your doctor see an image of your breast. This medicine is not used to detect other types of lesion receptors, including human epidermal growth factor receptor 2 (HER2) and progesterone receptor (PR).
Fluoroestradiol F 18 is a radiopharmaceutical. Radiopharmaceuticals are radioactive agents, which may be used to find and treat certain diseases or to study the function of the body's organs.
This medicine is to be given only by or under the direct supervision of a doctor with specialized training in nuclear medicine.
