摘　　要：目的探讨18F-FDG双时相显影在肺结节性病灶诊断与鉴别诊断的临床应用价值。方法回顾性分析43例18F-FDG双时相显影且经病理证实的肺结节性病例。其中男性31例,女性12例,年龄38～84岁。使用18F-FDG行全身或肺部PET/CT及双时相病灶扫描,依据PET图像、CT图像、PET/CT融合图像进行综合性分析。结果 43例肺结节性病灶的病例中,双时相显影诊断肺癌26例,病理证实23例;诊断可疑肺癌8例,病理证实5例;诊断良性病变9例,病理证实8例。结论对于肺结节性病灶,应用18F-FDG双时相显影可提高诊断的准确性。Objective To investigate the clinical application values of dual time phases imaging of 18F-FDG PET/CT to diagnosis of the diagnosis and differential diagnosis of pulmonary sarcoidosis focus.Methods A retrospective analysis was made in 43 patients（31 men,12 women and aged from 38 to 84 years）with detected by dual time phases imaging of 18F-FDG PET/CT and confirmed by pathological examination.They received the whole body or lung PET/CT and dual time phase focal scanning,and a comprehensive analysis was made according to the PET,CT images and PET/CT fusion images.Results Among the 43 subjects,26 ones were diagnosed as lung cancer by the dual time phase imaging and 24 ones were verified by pathological examination;8 ones were diagnosed as suspicious lung cancer by the dual time phase imaging and 5 ones were verified by pathological examination;9 ones were diagnosed as benign lesion and 8 ones were verified by pathological examination.Conclusion The application of dual time phase imaging of 18F-FDG PET/CT can improve the accuracy of the diagnosis of pulmonary sarcoidosis focus.
