- CT involvement score
- The severity of the lung involvement on the CT correlates with the severity of the
disease. The severity on CT can be estimated by visual assessment.
- < 5% involvement
- 5%-25% involvement
- 26%-49% involvement
- 50%-75% involvement
- > 75% involvement.
- The total CT score is the sum of the individual lobar scores and can range from 0 (no
involvement) to 25 (maximum involvement), when all the five lobes show more than 75% involvement.
