ABSTRACT
Objective To explore the CT features of ground-glass nodules. Methods A total of 104 cases of GGN le-sions were divided into three groups, 25 cases in preinvasive lesion group, 42 cases in minimally invasive adeno-careinoma group(MIA), 37 cases in invasive adenocarcinoma group (IAC), the lesion size, 3-dimensional ratio, 2-dimen-sional ratio, shape were analyzed and compared with pathological. Results ①All preinvasive lesions presented as pure GGN on CT image, MIA presented as pure GGN or mixed GGN on CT image, IAC most presented as mixed GGN on CT image; ②Speculation, lobulation, air-containing space and pleural indentation displayed gradually increasing from preinvasive lesions to MIA and IAC; ③There were statistically significant differences in lesion size, CT density, shape between the MIA and IAC groups (P<0.05); ④There were statistically significant differences in CT density values and long diameters of solid component of the lesions between the preinvasive lesion group and MIA group (P<0.05). Con-clusion Comprehensive analysis of the CT image features of GGNs, especially the solid component in the lesions, may help to the preoperative and differential diagnosis of preinvasive lesions, MIA and IAC, which is worth promoting the clinical application.
