81例恶性肺微小结节的影像学征象分析
Analysis of imaging characteristics of malignant solitary pulmonary nodule
摘要
Abstract
Objective To analyze the imaging characteristics of malignant solitary pulmonary nodular (SPN).Methods There were 81 patients with malignant SPN confirmed by operation and pathology collected in our hospital,and an analysis of their imaging characteristics was performed.Results In the 81 malignant SPN cases,there were 21 cases of pure ground-glass opacity (pGGO),24 cases of mixed ground-glass opacity (mGG0),36 cases of solid nodule (SN).The detection rate of lobulated and pleural retraction sign was lower in pGGO than in mGGO and SN (x2 was 21.13,28.56,respectively,P＜0.001).As the solid components of nodules increased,lobulated and pleural retraction sign were more easily observed (trend x2 were 18.64,28.28,P＜0.001).There were no significant differences in spiculation,air bronchogram and vascular convergence sign between the three types of malignant SPN (P＞0.05),and the incidence was high in all the three types.Conclusions The imaging characteristics of the three types of malignant SPN were different,however,the detection rate of vascular convergence sign was high in all the three types.Observing the relationship between SPN and blood vessels is more valuable in differentiating benign and malignant small SPN.关键词
