肺部CT中的“树枝发芽”(TIB)状表现反映了小气道和呼吸细支气管因粘液或炎症物质而致之嵌塞和扩张。最早描述于弥漫性全细支气管炎和播散性支气管内膜分枝杆菌结核中,近来也见于其它各种肺病。 作者观察了171例患者薄层(层厚1～1.5mm)CT表现,了解TIB在各种疾病中的发生率及其意

TIB-like appearances in lung CT reflect the caesarean section and dilatation of small airways and respiratory bronchioli due to mucus or inflammatory substances. The earliest description of diffuse panbronchiolitis and disseminated Mycobacterium tuberculosis tuberculosis, also recently found in a variety of other lung diseases.
