Abstract
Objective:To analyze the multi-slice spiral CT (MSCT) manifestation of lung adenocarcinoma with mixed ground-glass opacity (MGGO).Methods:112 lung adenocarcinoma patients with MGGO in our hospital from January 2013 to October 2015 were recruited as an observation group,and 80 pneumonia patients with MGGO were also selected as a control group.MSCT features including pleural indentation,vascular syndrome,clear boundary,lobulation and halo signs were compared between the two groups.Results:The proportions of pleural indentation,vascular syndrome,clear boundary,and halo sign of lung adenocarcinoma were significantly higher in the observation group than those in the control group (P ＜0.05).There were significant differences in the density,location,quantity,size and shape among adenocarcinoma in situ (AIS),minimally invasive adenocarcinoma (MIA) and invasive adenocarcinoma (IAC)with MGGO (P ＜0.05).The solid components in AIS and IAS mainly appeared with higher portion of vessels located in the close layers,central or eccentric growth,single nodule,diameter ＞5 mm,dotted or polygonal,irregularly shaped.The solid nodules were usually with higher proportion of vascular located in the lower layers,eccentric growth,multiple nodules,diameter ＜5 mm,round and oval shaped in MIA.Conclusion:MSCT characteristics might help to identify and diagnose lung adenocarcinoma with MGGO.关键词
