一、支气管体层摄影倾斜体层摄影可以观察气管、支气管的管腔、支气管周围淋巴结病变,还能显示支气管壁和支气管周围的病理改变,因之,对中央型肺癌的诊断价值较大。中央型肺癌支气管倾斜体层摄影所见: 1.向支气管腔内凸入的肿块阴影,自轻度局限性隆起至显著的息肉状或菜花状肿块; 2.支气管腔局限性狭窄和局部管腔不规则增厚;
1. Bronchigraphic Tomography Tomography can be used to observe the bronchial and bronchial lymph node lesions of the trachea and bronchi, as well as the pathological changes in the bronchial wall and peribronchial wall. Therefore, the diagnostic value of central lung cancer is relatively large. The bronchial oblique tomography of central lung cancer can be seen: 1. The shadow of the mass protruding into the bronchial cavity, from the slight limitation uplift to a prominent polypoid or cauliflower-like mass; 2. The bronchial cavity localized stenosis and partial lumen Irregular thickening;
