【摘要】 目的探讨18F-FDG PET/CT(18F-脱氧葡萄糖—正电子发射计算机断层扫描)在结直肠癌诊断中的应用价值.方法对186例结直肠癌行PET/CT检查的患者资料进行回顾性分析.根据PET/CT影像资料,对所有病例按肿瘤部位及肿瘤类型进行了分类,并将计算所得SUV(最大标准摄取值)与正常组织SUV进行比较.结果通过PET/CT显影,病例按部位分直肠癌112例、乙状结肠癌27例、盲肠癌17例、升结肠癌16例、降结肠癌14例;按肿瘤类型,隆起型68例、溃疡型57例、浸润型34例、胶样型27例.经计算癌灶SUV均较正常组织高,结果有统计学意义(P<0.05).结论 18F-FDG PET/CT检查对结直肠癌的诊断及其部位与分型有较高的应用价值.更多还原

【Abstract】 Objective To discuss the application value of18F-FDG PET/CT in diagnosis of colorectal cancer.Methods We retrospectively analyzed the data of 186 patients who were diagnosed as colorectal cancer by 18F-FDG PET/CT. We classifed all cases according PET/CT imaging into position group and type group,and calculated SUV(maximum standard uptake value) of tumor tissue, and compared with normal tissue. Results There were 112cases of rectal cancer,27 cases of carcinoma of sigmoid, 17 cases of carcinoma of cecum,16 cases of ascending colon carcinoma,14 cases of carcinoma of descending colon according to positions via PET/CT. There were 68 cases of protrude type,57 cases of ulcerative type,34 cases of infiltrating type,27 cases of colloid adenoma according types via PET/CT. The SUV of tumor tissue was higher than normal value,the difference had statistical significance.Conclusion 18F-FDG PET/CT has high application value in colorectal cancer diagnosis, positions and types.更多还原
