The axial images were acquired craniocaudally at shallow inspiration and included the body part extending from the thoracic inlet to upper abdomen (including the upper poles to midportion of the kidneys). High-resolution CT of the chest was obtained by using the following parameters; 120 kVp, 100–200 mA, 80 × 0.5 mm collimation and reconstructed at 0.5 mm slice thickness with a sharp reconstruction kernel. All of the patients underwent CT scans without contrast agent administration. CT images were reviewed in consensus by two thoracic radiologists (A.C and R.S). CT scores were assigned for the first scan that was obtained at hospital admission and follow-up CT scan of each patient to evaluate the extension of the lung involvement. A chest CT scoring system was used in which each lobe was given a score that was based on the following: score 0, no involvement; score 1, less than 5% involvement; score 2, 5–25% involvement; score 3, 26–49% involvement; score 4, 50–75% involvement; and score 5, greater than 75% involvement of the lobe. According to this scoring system, the minimum and maximum values of lung CT scores were 0 and 25, respectively [19–21]. Patients were divided into two groups based on the lung CT scores as follows, non-progressive group: patients with decreased or stable CT scores on the follow-up CT scan and progressive group: patients with increased CT scores on the follow-up CT scan.","tracks":[{"project":"2_test","denotations":[{"id":"33051758-16055695-31257","span":{"begin":1273,"end":1275},"obj":"16055695"},{"id":"33051758-32053470-31257","span":{"begin":1273,"end":1275},"obj":"32053470"}],"attributes":[{"subj":"33051758-16055695-31257","pred":"source","obj":"2_test"},{"subj":"33051758-32053470-31257","pred":"source","obj":"2_test"}]}],"config":{"attribute types":[{"pred":"source","value type":"selection","values":[{"id":"2_test","color":"#a593ec","default":true}]}]}}
