摘　　要：目的研究肺部CT不同阴影特征对肺部良恶性病变诊断的指导意义。方法1200例肺部CT检查时因肺部阴影住院的患者,分析组织病理学结果以及性别、年龄、病灶大小、肺部阴影特性、肺部CT双轨征与肺部病变的关系。结果组织病理学结果显示:恶性病变患者835例(69.58%),良性病变患者365例(30.42%)。恶性病变患者中男411例(49.22%),女424例(50.78%);良性病变患者中男213例(58.36%),女152例(41.64%);良恶性病变患者的性别比较差异具有统计学意义(P<0.05)。患者平均年龄为(56.00±10.89)岁,其中恶性病变患者主要集中在60~69岁,良性病变患者主要集中在50~59岁。肺部肿块患者中,恶性病变302例(75.31%),良性病变99例(24.69%);肺部结节患者中,恶性病变533例(66.71%),良性病变266例(33.29%)。肺部肿块患者的恶性病变占比大于肺部结节患者,差异具有统计学意义(P<0.05)。恶性病变患者的毛刺征发生率为64.55%,分叶征发生率为73.89%,胸膜凹陷征发生率为32.22%,均高于良性病变患者的59.59%、32.05%、20.27%,差异具有统计学意义(P<0.05)。当肺部阴影中存在毛刺征、或存在分叶征患者,或存在胸膜凹陷征,更有可能是恶性病变;无论是肺部阴影面积大与小,出现毛刺征、分叶征和胸膜凹陷征时,患者恶性病变的几率更高。肺部阴影、肺部肿块、肺部结节患者良恶性病变发生双轨征的几率比较差异无统计学意义(P>0.05)。结论女性患者恶性病变的可能性高于男性,而男性患肺鳞癌的可能性高于女性,当肺部肿块或者结节中有毛刺征、分叶征或胸膜凹陷征时发生恶性病变的几率更高。Objective To study the guiding significance of different pulmonary CT shadows in the diagnosis of benign and malignant lesions.Methods 1200 patients hospitalized for pulmonary CT shadows,and the histopathological findings and the correlation between gender,age,lesion size,lung shadow characteristics,pulmonary CT dual-track sign and pulmonary lesions were analyzed.Results Histopathological results showed that there were 835 patients(69.58%)with malignant lesions and 365 patients(30.42%)with benign lesions.Among patients with malignant lesions,there were 411 males(49.22%)and 424 females(50.78%);among patients with benign lesions,213(58.36%)were males and 152(41.64%)were females;the difference in the genders of patients with benign and malignant lesions was statistically significant(P<0.05).The mean age of the patients was(56.00±10.89)years,with patients with malignant lesions concentrated in the age group of 60-69 years and patients with benign lesions concentrated in the age group of 50-59 years.Among patients with pulmonary masses,302 cases(75.31%)had malignant lesions and 99 cases(24.69%)had benign lesions;among patients with pulmonary nodules,533 cases(66.71%)had malignant lesions and 266 cases(33.29%)had benign lesions.The percentage of malignant lesions in patients with pulmonary masses was greater than that in patients with pulmonary nodules,and the difference was statistically significant(P<0.05).The incidence of burr sign in patients with malignant lesions was 64.55%,the incidence of lobar sign was 73.89%,and the incidence of pleural identation sign was 32.22%,all of which were higher than 59.59%,32.05%,and 20.27%in patients with benign lesions,and the differences were statistically significant(P<0.05).When there was a burr sign in the pulmonary shadow,or a patient with a lobar sign,or a pleural depression sign,it was more likely to be a malignant lesion;regardless of whether the area of pulmonary shadow was large or small,the incidence of malignant lesions was higher when there were signs of burrs,lobes,
