胸部块影X线、CT与纤维支气管镜对照分析

目的确定胸部块影的X线与CT特征及其与纤维支气管镜所见的关系。材料和方法收集25例肺部块影，均行胸部正侧位片及CT平扫和增强检查，采用纤支镜检查对照分析。结果普通胸部X线诊断符合率64．0％，CT诊断符合率84．0％，对胸部疾病的敏感性和特异性CT优于常规胸片。纤支镜检查符合率88．0％，纤支镜检查对肺周围型病变存在一定局限性，可在CT引导下穿刺活检同样能得到准确诊断。结论胸部X线、CT检查对多数疾病可作出准确诊断，肿块阴影、结节阴影和肺门肿块多见于肿瘤，班片状阴影多见于炎症和结核。纤支镜检查对胸部块影的病因和性质能提供可靠依据。

Radiographic and CT features of thoracic masses and their relation to the findings of bronchial endoscopy

Objective To determine the radiographic and CT features of thoracic masses and their relation to the findings of bronchial endoscopy.Methods Chest film (PA and lateral view) and CT (pre-enhancement and post-enhancement) findings in 25 patients with thoracic mass were reviewed and compared with the findings of bronchial endoscopy.Results The diagnostic correspondency was 64% on chest film.84% on CT.The sensitivity and specificity of CT were higher than that of chest film.The correspondancy of bronchial endoscopy was 88%.The value of bronchial endoscopy was limited in the diagnosis of peripheral lesions which could be accurately diagnosed by CT guiding aspiration biopsy.Conclusion Most of the lung diseases can be diagnosed by chest film and CT.Pulmonary tumors usually displayed as mass,nodular and hilar mass while inflammation and TB usually displayed as mottled-patchy shadow in the lung.Bronchial endoscopy can provide the reliable evidences of the cause and nature of the lung mass.
