Radiological criteria for calling a shadow in CXR as consolidation are:
- Lobar or Segmental Density
The density should either correspond to lobe or segment of Lung.
- Air Bronchogram
Presence of air bronchogram would confirm that it is an alveolar
- 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
