摘　　要：目的回顾性分析肺良恶性孤立性磨玻璃密度病灶的影像学形态特点,以期望提高这类疾病诊断的准确率。方法对2013年10月-2016年5月间在我院行CT扫描发现肺内存在孤立性磨玻璃密度病灶且有病理结果的56例患者的原始数据进行回顾性分析。结果 56例患者中,良恶性GGO组男女性别比例、年龄、病灶平均截面大小、病灶分布的差异没有统计学意义(P>0.05);恶性GGO更容易出现支气管截断征、分叶征、毛刺征、小气泡、胸膜凹陷征、血管集束征等(P<0.05);肺良恶性部分GGO中实性部分CT值的差异没有统计学意义(P>0.05)。结论肺部分实性GGO病灶为恶性的几率高于肺纯GGO病灶,当肺GGO病灶出现分叶征、毛刺征、血管截断征、小气泡、血管集束征时,病灶为恶性肿瘤的可能性较大。Objective Analyze the imaging features of pulmonary benign and malignant solitary ground glass opacity(GGO)in order to improve the diagnostic accuracy of the disease.Methods A retrospective analysis of medical imaging in 56 patients with lung GGO science data and pathological data were conducted during the October 2013-May 2016.Results In 56 patients,the gender ratio,the age,the average cross-sectional size of the lesion,the difference of the lesion distribution was not statistically significant between benign and malignant GGO groups(P>0.05).Malignant GGO more prone to present bronchial truncation sign,lobulation,burr sign,small bubbles,pleural indentation,vascular convergence sign(P<0.05).Differences of CT values in the solid part of lung benign and malignant solid GGO were not statistically significant.Conclusion The malignant probability of partial solid GGO lesions was higher than that of pure GGO.When the lung GGO lesions presented bronchial truncation sign,lobulation,burr sign,small bubbles,pleural indentation,vascular convergence sign,the lesions were more likely to be malignant tumors.
