Assessment of rapidly progressive interstitial lung disease (RP-ILD) by computed tomography (CT) scores. A Assessment of RP-ILD by CT ground glass opacity (GGO) scores (G-scores): (a) thin-section CT scan shows small areas with GGO compared with normal parenchyma at the right lower lobe (mild GGO = 1); (b) CT scan shows extensive GGO that could be easily identified when compared with the normal parenchyma at the right lower lobe (moderate GGO = 2); (c) thin-section CT scan shows areas with diffuse GGO at the right lower lobe (severe GGO = 3). B Assessment of RP-ILD by CT fibrosis scores (F-scores): (a) thin-section CT scan shows areas with thickened interlobular septum or predominant peripheral fibrosis (mild fibrosis = 1). (b) CT scan shows extensive fibrosis that could be easily identified when compared with normal parenchyma at the right lower lobe (moderate fibrosis = 2), moderate fibrosis and bronchiolectasis. (c) thin-section CT scan shows areas with diffuse fibrosis at the right lower lobe (severe fibrosis = 3). Note honeycombing, bronchiectasis, peribronchovascular thickening, and subpleural cysts
