青岛地区646例肺团块或肺结节患者影像学特征的分析

Survey of computed tomography imaging characteristics of 646 pulmonary nodules or lung masses in Qingdao

目的描述肺团块/肺结节病灶的特征及病因,为临床判断此类病变的良恶性提供依据。方法在青岛5个研究中心收集获得肺团块/肺结节病理学资料的病例646例,比较患者胸部CT检查在肺部良恶性疾病中的表现,并对其构成比的差异进行统计学分析。结果毛刺征、胸膜凹陷征和支气管充气征在肺良恶性病变中的差异有统计学意义(P<0.05),其中毛刺征和胸膜凹陷征在肺部恶性组的构成比高于肺部良性组,而支气管充气征在肺部良性组的构成比高于肺部恶性组。结论在肺团块/肺结节病灶中,毛刺征和胸膜凹陷征提示肺恶性病变,而支气管充气征提示肺良性病变。

Objective To describe the etiology and computed tomography（CT） characteristics of pulmonary nodules and lung masses in order to provide a basis for differentiating benign and malignant masses. Methods CT chest scans were performed on 646 patients from five research centers in Qingdao;patients had been diagnosed with benign or malignant masses based on pathology.Scans for the two types of masses were compared using statistical analysis. Results CT scans for benign and malignant masses differed significantly in sentus, pleural indentation and air bronchogram results. Conclusion Spiculation and pleural indentation on CT scans suggest that the lung mass or pulmonary nodule may be malignant, while air bronchogram suggests it may be benign.
