Hello, we will continue to learn some terms English in Diagnostic Imaging And today I will learn about lung lesions when reading chest X-ray.

Lung abnormalities mostly present as areas of INCREASED DENSITY, which can be divided into the following patterns:

Pulmonary abnormalities most often manifest as regions OF INCREASED, which can be divided into the following categories:

1. Consolidation / kənˌsɑːlɪˈdeɪʃn / = airspace shadowing / ˈerspeɪs ˈʃædəʊɪŋ /: solidification

• Features of consolidation on a chest radiograph: Features of consolidation on a chest radiograph:
  • Patchy shadowing: Shadows with unknown edges (patchy holes)
  • Lobar or segmental density: lobe or segmental density
  • Air bronchogram: air bronchogram
  • No loss of lung volume: no loss of lung volume.

2. Atelectasis / collapse / = collapse / collapse /: collapse of the lung

• General features of collapse on a chest radiograph include: General features of atelectasis on chest radiographs include:
  • An increase in density, representing lung devoid of air (whiteness): Increase density, represent lung without air (white)
  • Signs indicating decreased lung volume: Signs indicating decreased lung volume:
    • displacement of mediastinum / trachea towards the collapsed lung: mediastinum / trachea shift toward the collapsed lung
    • elevation of the hemidiaphragm: elevation diaphragm arch
    • compensatory over- inflation of adjacent lobes or opposite lung: compensated hyperventilation of the adjacent lobes or the opposite lung.

3. Nodule (<3cm) or mass (> 3cm): note (<3cm) or block (> 3cm)

• Solitary pulmonary node – SPN: Single pulmonary nodule

4. Interstitial / ˌɪn tərˈstɪʃəl /: interstitial tissue

• Reticular / rɪˈtɪk yər /: grid
• Nodular / ˈnɒdʒ ə lər /: note type
• High attenuation / haɪ əˌtɛn yuˈeɪ ʃən /: high density
• Low attenuation / loʊ əˌtɛn yuˈeɪ ʃən /: low density
  • emphysema / ˌɛm fəˈsi mə /: emphysema
  • cystic disease / ˈsɪstɪk dɪˈziz /: cystic disease
