【摘要】 目的探讨中心型肺癌的CT早期诊断。方法回顾总结由病理证实56例中心型肺癌的首次CT表现。结果56例中首次CT检查均表现为不同程度的阻塞性肺气肿、阻塞性肺炎、阻塞性肺不张的间接早期征象,而无明显气道狭窄、消失及肺门部肿块等直接征象。结论中心型肺癌早期CT直接征象少,难显示;间接征象多,易发现,但缺乏特征性,误诊高。CT薄层扫描加重建有助于发现直接征象,结合支气管镜活检可提高早期诊断。更多还原

【Abstract】 Objective To discuss the clinical significance of the CT on early diagnosis for central lung cancer.Methods The first CT imagings of 56 patients,whose disagnosis were determined by histopathology examination,were analyzed in retrospective method.Results All patients,in 56 case,show different extent indirectively syndrome of lung cancer,for example: obstructive pulmonary emphysema,obstructive pneumonia,obstructive pulmonary atelectasis.There were little directive evidence for lung cancer such as airway stenosis,airway disappear,hilar mass.Conclusion There are little direct evidences in CT scan images of central lung cancer in early stage,but there are much indirect evidences in CT scan images.So CT thin scanning with rebuilding images is conducive to find out direct evidences of lung cancer.CT thin scan with bronchoscopy and biopsy were recommendated in order to diagnose the lung cancer in early stage.更多还原
