Differential diagnosis on HRCT
Most of our knowledge about imaging findings in interstitial lung disease comes from
four patterns: ... and what kind of pattern ... the most common pattern ... The ground-glass pattern ... The cystic pattern
The fourth pattern includes abnormalities that result in decreased lung attenuation or air-filled lesions.
These include:
- Emphysema
