The present study compared 68Ga-FAPI and 18F-FDG PET/CT in a patient with GSRCC (gastric signet-ring cell carcinoma). In this case, 68Ga-FAPI PET/CT shows much higher tumor-to-background contrast of primary tumor and reveals more metastatic lesions than 18F-FDG PET/CT. This case demonstrates that 68Ga-FAPI PET/CT outperforms 18F-FDG in identifying both primary and metastatic lesions in GSRCC.
本研究比较了 68Ga-FAPI 和 18F-FDG PET/CT 在胃印戒细胞癌（GSRCC）患者中的应用。在该病例中，68Ga-FAPI PET/CT 显示原发性肿瘤的肿瘤与背景对比更高，并比 18F-FDG PET/CT 显示更多的转移病灶。该病例表明，68Ga-FAPI PET/CT 在识别 GSRCC 的原发性和转移性病灶方面优于 18F-FDG。
