Ga-67 uptake in diethylstilbestrol-induced gynecomastia. Experience with six patients

Six patients who had been treated with diethylstibestrol (DES) for prostatic cancer had symmetrical breast uptake of Ga-67. Of these patients, five proved to have DES-induced gynecomastia. The minimum dose and administration period of DES required for Ga-67 uptake in gynecomastia is discussed.
