Lung fibrosis in systemic sclerosis - grading by Wells et al.
Wells classification of lung involvement in systemic sclerosis is a quantitative scoring method of disease extent and severity. All lobes are scored independently. Maximum score for each lobe is 5.
| Grade | Description |
|---|---|
| 1 | Ground glass opacity alone |
| 2 | Ground glass opacity > reticular pattern extent |
| 3 | Ground glass opacity = reticular pattern extent |
| 4 | Ground glass opacity < reticular pattern extent |
| 5 | Reticular pattern alone |
