Table 2 : HRCT scoring system according to Gay SE et al., [13].


Score Alveolar Interstitial

0 No alveolar disease No interstitial disease
1 GGO < 5%      Septal thickening, no honeycombing
2 GGO < 25% HC/ septal thickening < 25%
3 GGO 25-49% HC/septal thickening 25-49%
4 GGO 50-75%  HC/septal thickening 50-75%
5 GGO > 75% HC/septal thickening > 75%

prominent convexity of the right ventricle, and peak of the right cupola of diaphragm.
Mean interstitial and alveolar scores were counted.
GGO = ground glass opacity,
HC = honeycombing.
