Clinical diagnostic value of high resolution CT signs for benignity or malignancy of GGN patients
Objective To explore the clinical diagnostic value of high resolution CT signs for benignity or malignancy of pulmonary ground-glass nodules(GGN)patients.Methods 82 patients with GGN were divided into benign group(8 patients)and malignant group(74 patients)according to benignity or malignancy of tumors.All patients underwent high-resolution CT.The high-resolution CT features(lesion size,lesion shape,lobular sign,burr sign,interface,cystic translucent shadow,vacuole sign,bronchus sign,vessel convergence,density,pleural indentation)of the two groups were compared.Multivariate Logistic regression was used to analyze the imaging risk factors of patients with malignant GGN,and the diagnostic value of imaging detection for malignant GGN was analyzed.Results There were no significant differences in lesion size,lesion shape,vacuole sign,bronchial sign,vessel convergence and pleural indentation between the two groups(P>0.05).In the malignant group,55 cases had lobed signs,56 cases had burr signs,54 cases had cystic transparent light,45 cases had clear smooth interface,20 cases had clear frizz interface,9 cases had fuzzy interface,and 20 cases had pure ground-glass nodules(PGGN)density,which was significantly different from 1,2,1,1,1,6,6 cases in the benign group(P<0.05).Logistic regression model showed that lobed sign,burr sign,cystic translucent shadow,interface and density were the influencing factors of malignant GGN(P<0.05).The highest diagnostic value of high-resolution CT for malignant GGN was the lobular sign,and the lowest was the interface.Conclusion The application of high-resolution CT for patients with GGN has a better effect in discriminating its benignity or malignancy,and the highest diagnostic value of lobular sign can provide a reference for clinical diagnosis and differentiation.
