Abstract
A 40-year-old woman with suspected recurrent HER2-positive gastric cancer underwent both F-FDG PET/CT and Ga-ZHER2 PET/CT. Both scans revealed multiple lesions in bones and the left supraclavicular lymph node. Compared with F-FDG, Ga-ZHER2 PET/CT showed better image contrast, especially in the bone lesions.
