PDFAbstract
Objective To explore the CT findings of pulmonary ground glass density nodule (GGNs) and the diagnostic value. Methods The pathological data and CT imaging signs of 68 patients with GGNs were retrospectively analyzed. The data, such as size, nature, lobulation, burr, boundary, vocule sign, size and content of solid components were analyzed statistically. Results There were statistically significant differences in the type, size, lobulation, burr, boundary, solid components and the content between preinvasive lesions and microinvasive adenocarcinoma (P<0.05), but there was no significant difference in air bronchogram, vocule sign or pleural indentation (P>0.05). Logistic regression analysis showed that the size, type, lobulation, burr and boundary of lesions were independent influencing factors of preinvasive lesions and microinvasive adenocarcinoma. Conclusion The size, nature, lobulation, burr and boundary are independent influencing factors of preinvasive lesions and microinvasive adenocarcinomas. They can be used as a reference for CT imaging diagnosis.
