ReviewCurrent applications of PET imaging of sex hormone receptors with a fluorinated analogue of estradiol or of testosterone.
Currently, the most frequent approach in the oncologic applications of positron emission tomography (PET) is detecting the hypermetabolic activity of the cancer tissue. A more specific approach, which may be complementary, is detecting the overexpression of receptors. In this review article, we aim to evaluate the results that are currently available for PET imaging of the sex hormone receptors in clinical oncology. ⋯ From absorbed dose values previously published for FES by the team of University of Washington School of Medicine at Seattle, and for FDHT by the teams of Memorial Sloan-Kettering Cancer Center at New York and of Washington University at St. Louis, we applied the coefficients of ICRP publication 103 and calculated an effective dose per unit of injected activity of 0.023 mSv/MBq for FES and 0.018 mSv/MBq for FDHT. The radiation exposure is of the same order of magnitude as with FDG.
