对胸部Ｘ线检查示不同类型阴影患者１３２例进行纤维支气管镜（纤支镜）检查，比较分析两种检查结果。团块状阴影、团块状影并肺不张的影像征主要见于肺肿瘤；斑片状阴影、斑片状影并肺不张多见于炎症、结核。纤支镜检确诊１２５例，确诊率９４．７％，肺肿瘤的纤支镜确诊率９４．９％，肺结核的确诊率９２％，炎症的确诊率１００％，胸部Ｘ线检查与纤支镜检符合率８０．８％。对比分析说明：胸部Ｘ线检查可为纤支镜检提供重要的影像资料，但对病变性质、类型等的确定多有不足。纤支镜检确诊率高，对病变的性质、类型、病因等能提供可靠的依据，较好的弥补了胸部Ｘ线检查的不足。
132 cases of different types of shadow in chest X-ray examination were examined by fiberoptic bronchoscopy, and the results of two tests were compared and analyzed. Massive shadow, mass shadow and atelectasis of the main signs of lung cancer seen in the image; patchy shadow, patchy film and atelectasis more common in inflammation, tuberculosis. Bronchoscopy confirmed the diagnosis of 125 cases, the diagnosis rate of 94.7%, bronchoscopy of lung tumors 94.9%, 92% confirmed tuberculosis, the diagnosis of inflammation 100%, chest X-ray examination and bronchoscopy Check coincidence rate of 80.8%. Comparative analysis shows that: chest X-ray examination can provide important imaging information for the bronchoscopy, but the nature of the lesion, the type of determination and more. Bronchoscopy confirmed the high rate of the nature of the disease, type, cause can provide a reliable basis, a better make up for the lack of chest X-ray examination.
