Utility of F-fluoroestradiol over F-fluorodeoxyglucose positron emission tomography/computed tomography in the initial diagnosis of over 90 metastatic lesions in a patient with metastatic estrogen receptor-positive breast cancer.

Proper staging workup and diagnosis of metastatic lesions is crucial prior to surgical treatment.F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) is often included in the staging workup of locally advanced breast cancer.
