摘　　要：目的:探究18F-脱氧葡萄糖(18F-FDG)正电子发射型计算机断层扫描(PET-CT)在肺癌诊断及分期中的应用。方法:选取南阳市中心医院2017年12月至2019年12月期间收治的95例疑似肺癌患者,以病理诊断为“金标准”,计算18F-FDG PET-CT诊断效能,并参照病理TNM分期,判断PET-CT显像在肺癌分期中的应用。结果:金标准确诊肺癌91例、肺结核3例、肺纤维瘤1例,TNMⅠ期31例、Ⅱ期27例、Ⅲ期24例、Ⅳ期9例;PET-CT显像显示肺癌88例,确诊肺癌85例,诊断准确度、灵敏度分别为90.53%、93.41%,与病理分期比较Ⅰ~IV期诊断准确率分别为90.32%、55.56%、54.17%、88.87%。结论:18F-FDG PET-CT显像诊断肺癌准确度和Ⅰ期鉴别诊断准确率均较高,可为肺癌早期诊断提供科学依据。Objective To explore the application of 18F-deoxyglucose(18F-FDG)positron emission computed tomography(PECT)in the diagnosis and staging of lung cancer.Methods 95 patients with suspected lung cancer treated in Nanyang Central Hospital from December 2017 to December 2019 were selected.Pathological diagnosis was used as the"gold standard",the diagnostic efficacy of 18F-FDG PET-CT was calculated,and the application of PET-CT phenomenon of lung cancer staging was judged by referring to pathological TNM staging.Results 91 cases of lung cancer,3 cases of pulmonary tuberculosis,1 case of pulmonary fibroma,31 cases of TNM stageⅠ,27 cases of TNM stageⅡ,24 cases of TNM stageⅢand 9 cases of TNM stageⅣwere diagnosed according to the gold standard.PET-CT imaging showed 88 cases of lung cancer and 85 cases of lung cancer were diagnosed.The diagnostic accuracy and sensitivity were 90.53%and 93.41%respectively.Compared with pathological stages,the diagnostic accuracy of stageⅠ~Ⅳwere 90.32%,55.56%,54.17%and 88.87%respectively.Conclusion 18F-FDG PET-CT imaging has high accuracy in the diagnosis and stageⅠdifferential diagnosis of lung cancer,which can serve as a scientific basis for the early diagnosis of lung cancer.
