Anhvanyds – Lectures – English Diagnostic Image Terminology

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.
  1. 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.
  1. Nodule (<3cm) or mass (> 3cm): note (<3cm) or block (> 3cm)
  • Solitary pulmonary node – SPN: Single pulmonary nodule
  1. 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
