Med Imaging- Lungs Pt. 2

Walls of the bronchi thickened by inflammation or infection, may be diffuse or focal

Bronchiectasis

CXR in affected individuals is often normal or shows non-specific findings

Bronchiectasis

Bronchiectasis

Tram track lines

Bronchiectasis

Condition that can cause bronchiectasis

Cystic fibrosis

Lung tissues with air space but no alveoli thats less than 1 cm in diameter

Bleb

Lung tissues with air space but no alveoli thats greater than 1 cm in diameter

Bullae

RUL bullae

Flattening of hemidiaphragms

& blunting of costophrenic angles, Increased AP diameter (barrel chest), bullae or large air cavities indicates

hyperinflation

COPD/Emphysema

COPD/Emphysema

Occurs when alveoli become deflated (complete or partial collapse) or possibly filled with alveolar fluid

Atelectasis

Atelectasis

Atelectasis (RUL)

Linear atelectasis (often seen post-op)

Asthma (hyperinflation with tram lines)

asthma

Air in the pleural space that causes collapse of the lung usually seen in the apices if pt is upright
