Radiological criteria for calling a shadow in CXR as consolidation are:

  1. Lobar or Segmental Density
    The density should either correspond to lobe or segment of Lung.
  2. Air Bronchogram
    Presence of air bronchogram would confirm that it is an alveolar process.
  3. No Loss of Lung Volume
    In early stages of consolidation the volume of lung increases. In later stages there can be some amount of loss of lung volume due to secretions obstructing airways. As a general rule there is no significant loss of lung volume in consolidation

You have the option to review consolidation of each lobe and review pathology by clicking options given in the adjacent box.
