Abstract
Objective:To investigate and control analyse the 18F-FDG PET/CT features of lung adenocarcinoma presenting as isolated ground-glass nodules (GGN).Methods:Sixty-eight lung adenocarcinoma presenting as isolated GGN confirmed by surgery pathology were included in this study.The lesions were divided into three groups:precancerous lesions(atypical adenomatous hyperplasia(AAH) and adenocarcinoma in situ(AIS)),microinvasive adenocarcinoma(MIA),invasive adenocarcinoma(IAC).The lesion size,solid portions,morphological feature,metabolism characteristic on the preoperative 18F-FDG PET/CT images in the three groups were analyzed and compared with pathological results.The data were statistically analyzed using SPSS 17.0.Results:The lesion size,solid portions,morphological feature,SUVmax gradually increased from precancerous lesions to IAC.There were statistically significant differences in lesion size and solid portions between the precancerous lesions and MIA groups (P＜0.05).There were statistically significant differences in the lesion size,solid portions,morphological feature and metabolism characteristic between MIA and IAC groups(P＜0.05,all).Conclusion:Comprehensive analysis of the 18F-FDG PET/ CT image features of GGN,may be helpful for the diagnosis and distinguish diagnosis of precancerous lesions,MIA and IAC.关键词
