CT SEVERITY SCORE Severity score is assigned by scoring the percentages of each of the five lobes that is involved: < 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 ranges from 0 (no involvement) to 25 (maximum involvement).
