68Ga-ZHER2 PET/CT Reveals HER2-Positive Metastatic Gastric Cancer With Better Image Quality Than 18F-FDG

Abstract A 40-year-old woman with suspected recurrent HER2-positive gastric cancer underwent both 18 F-FDG PET/CT and 68 Ga-ZHER2 PET/CT. Both scans revealed multiple lesions in bones and the left supraclavicular lymph node. Compared with 18 F-FDG, 68 Ga-ZHER2 PET/CT showed better image contrast, especially in the bone lesions.
