Recognition of which interlobar fissure in the right lung is major or minor is important in chest radiography. Based on assessment of the interlobar fissure, the location of diseases or the degree of expansion of the lobes is comprehensible. As a general rule, the major fissure is not seen in normal cases. However, the major fissure is visualized in the presence of volume loss of the lower lobe. Although the medial end of the minor fissure is at the intermediate artery between the upper and lower lobe bronchi, that of the major fissure is continuous to the central portion of the mediastinum. The following cases will be presented: post-pleuritis, atelectasis of the superior segment of the lower lobe (S6), obstructive pneumonia in the middle and lower lobes due to stenosis of the intermediate bronchus, pneumonia of the upper lobe, and superior accessory fissure with atelectasis of the upper lobe.
在胸部X线摄影中，识别右肺的哪条叶间裂是主裂还是副裂很重要。基于叶间裂的评估，疾病的位置或肺叶的膨胀程度是可以理解的。一般来说，正常情况下看不到主裂。然而，当下叶出现容积缩小 时，主裂会显影。虽然副裂的内侧端位于上、下叶支气管之间的中间动脉处，但主裂的内侧端与纵隔中央部分相连。将展示以下病例：胸膜炎后、下叶上段（S6）肺不张、中间支气管狭窄导致的中、下叶阻塞性肺炎、上叶肺炎以及伴有上叶肺不张的上副裂。
