Utility of 18F-fluoroestradiol PET / CT in the differential diagnosis of estrogen receptor-positive breast cancer: case series

Breast cancer is one of the most common female cancers and the leading cause of cancer death in women. The method of positron emission tomography, combined with computed tomography, makes it possible to assess not only anatomical and structural, but also metabolic changes in tumor tissue. The increased accumulation of 18F-fluoroestradiol in the pathological focus correlates with the estrogen receptor-positive status of the tumor, which is confirmed by tissue immunohistochemistry studies. The receptor status of a tumor formation fundamentally affects the choice of therapeutic tactics. The presented clinical examples demonstrate the capabilities of positron emission tomography, combined with computed tomography, with 18F-fluoroestradiol in the diagnosis of the estrogen receptor-positive tumor lesions.
