众所周知．支气管充气征在渗出感染性病变中有着重要的价值，尽管随着CT的应用，部分肺癌病变亦可存有支气管充气征[1、2]。我们观察．感染病变中存有的支气管充气征随扫描体位的改变有很大的变化。现就其结果作以下分析。材料与方法采用SIEMENSDR3，岛津4500．ELSCINTCTTWIN。
We all know. Bronchial airway sign has an important value in exudative infectious disease, although with the application of CT, some lung cancer lesions may also have bronchial airway sign [1,2]. We observe. Inflammatory bronchial signs of bronchial congestion changes with the scan position has changed a lot. Now the result of the following analysis. Materials and methods using SIEMENSDR3, Shimadzu 4500. ELSCINTCTTWIN.
