Interstitial - involvement of the supporting tissue of the lung parenchyma resulting in fine or coarse reticular opacities or small nodules.
7 Νοε 2023 · Atelectasis describes the loss of lung volume due to the collapse of lung tissue. It can be classified according to the pathophysiologic mechanism (eg, compressive atelectasis), the amount of lung involved (eg, lobar, segmental, or subsegmental atelectasis), or the location (ie, specific lobe or segment location).
1 Μαΐ 2021 · The lobar bronchus of the LUL has an upper branch which bifurcates into apical and posterior bronchi (B1 + B2) usually with a common origin and anterior bronchus (B3); and a lower or lingular branch which bifurcates into superior (B4) and inferior (B5) bronchi.
