| Abstract: | Purpose] To assess the clinical application of 18 F-FDG PET/CT imaging in the diagnosis for gastric cancer.Methods] Forty-nine gastric cancer patients proven by gastroscopy and histopathological examination received 18 F-FDG PET/CT imaging.The 18 F-FDG PET/CT diagnostic results were compared with pathology,other imaging findings and clinical follow up.Results] 18 F-FDG PET/CT was positive in 44 cases with positive rate 89.8%（44/49）.18 F-FDG PET/CT scan for lymphatic metastasis resulted in a sensitivity of 82.1%（32/39）.18 F-FDG PET/CT scan for distance metastasis resulted in a sensitivity of 91.6%（11/12）.Conclusion] 18 F-FDG PET/CT imaging is sensitive for finding primary lesion,lymphatic metastasis and distance metastasis with a higher diagnostic value for gastric cancer. |
