Q
What causes air space opacification?
A
- Fluid (or tissue) within the lung that usually contains air - i.e water, blood, pus - i.e cancer

Q
What are the types of descriptor terms for opacification
A
- Focal - Multifocal asymmetrical - Lobular (lobe of lung) - Patchy (Incomplete airspace filling with air filled region, opp = confluent) -> Central or symmetrical Distribution: Peripheral / central or perihilar, symmetrical or asymetrical
