Abstract

Objective To analyze the 18F-FDG PET/CT imaging application value in patients with gastric cancer after treatment follow-up. Methods A total of 52 cases of gastric cancer patients from April 2011 to April 2013 were selected as the research object, and compare the follow-up diagnostic accuracy of CT and 18F-FDG PET/CT imaging. Results There were 24 cases of gastric cancer recurrence and metastasis (20 cases of distant metastasis, 4 cases of recurrence in situ). The diagnosis accuracy rate of recurrence and metastasis by 18F-FDG PET/CT was 87.5%, significantly higher than 58.3% of CT, the difference was statistically significant(P<0.05). Conclusion 18F-FDG PET/CT imaging in patients with gastric cancer follow-up can be effectively reflected the recurrence and metastasis and could be the basis for the further treatment, which has significant application value.
