The concept
The concept of this website is based on a previous site that was founded in 2008 and is still up and running. The website is composed as a book, where all sources are properly referenced, according to a good practice in scientific publications.Didn't find a classification?

Lung fibrosis - semiquantitative grading by Warrick et al.
Warrick classification of lung involvement in interstitial lung disease is a quantitative scoring method of disease extent and severity. The grading involves the following features of the disease:
| Feature | Grading |
|---|---|
| Global disease extent | Estimated to the nearest 5% |
| Extent of reticulation | Proportion of total disease extent |
| Extent of ground-glass | Proportion of total disease extent |
| Coarseness of reticulation |
|
The features are assessed at five levels:
- Origin of the great vessels
- Main carina
- Pulmonary venous confuence
- Halfway between levels 3 and 5
- Immediately above the right hemidiaphragm
Total disease extent corresponds to the mean of the percentage of disease at each level.
