• 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.
