Chest imaging
DISEASE
Chest radiographs and high-resolution computed tomography of the chest (HRCT) were routinely performed to assess disease response according to local guidelines (thin-section images CT of 1–1.5 mm with a high spatial frequency reconstruction algorithm at 120 kV and approximately 240 mAs). All HRCT scans were evaluated by a specialist thoracic radiologist. Discrepant interpretations were discussed in the multidisciplinary team meeting until consensus was reached.
