  		Figure 1a. (a) Transverse thin-section CT scan of right lower lobe in a 25-year-old woman with SARS (obtained at day 3 after admission) shows two areas of ground-glass opacification, with thickened interlobular septa giving crazy-paving appearance. (b) Follow-up CT scan after discharge (obtained at day 27 after admission) shows almost complete resolution of lung abnormalities. Small patches of residual ground-glass opacification and septal thickening are still present.

  		Figure 2a. (a) Transverse conventional CT scan in 33-year-old man with SARS (obtained at day 4 after admission) shows ground-glass opacification. (b) Follow-up thin-section CT scan (obtained at day 46 after admission, 29 days since discharge) of the corresponding area shows evidence of fibrosis, such as parenchymal bands, irregular interface, and traction bronchiectasis.

  		Figure 3. Transverse thin-section CT scan in 36-year-old man at follow-up (obtained at day 43 after admission, 26 days since discharge) shows evidence of fibrosis. Large areas of ground-glass opacification are still present, both surrounding the areas of fibrosis and in other regions.
