On conventional chest radiographs, an area of diminished vascularity usually indicates focal disease. On CT scans of the chest, however, there is often a focal vascular deficiency in the right mid-lung that appears to be normal. In a study of 50 patients, diminished vascularity was noted at the level of the bronchus intermedius on 92% of the scans. The anatomical basis for this finding is discussed.
在传统胸部X光片上,血管减少的区域通常提示局灶性疾病。然而,在胸部CT扫描中,右肺中叶经常出现看似正常的局灶性血管缺失。在一项针对50名患者的研究中,92%的扫描显示在中间支气管水平存在血管减少。本文讨论了这一发现的解剖学基础。
