Table 3 Revised high-resolution CT scoring system with nine different parameters and a total score of 50

		Scoring per lobe
1	Linear or triangular subpleural opacities	0 = absent, 1 = present
		Maximum score = 6
2	Decreased pulmonary attenuation	0 = absent, 1 = one lobe
	Hypoattenuation (“mosaic perfusion”) in inspiration	Maximum = 6
3	Decreased pulmonary attenuation	0 = absent, 1 = one lobe
	Hypoattenuation (“air trapping”) in expiration	Maximum = 6
4	Bronchus/bronchiole: artery diameter ratio	0 = absent, 1 = one lobe
		Maximum = 6
5	Bronchiectasies	0 = absent, 1 = one lobe
		Maximum = 6
6	Peribronchial thickening	0 = absent, 1 = one lobe
		Maximum = 6
7	Bullae	0 = absent, 1 = one lobe
		Maximum = 6
8	Emphysema	0 = absent, 1 = one lobe
		Maximum = 6
9	Collapse/consolidation	0 = absent, 1 = subsegmental, 2 = segmental
