Obliterative bronchiolitis: individual CT signs of small airways disease and functional correlation.

摘要: PURPOSE: Individual features of small airways disease depicted at computed tomography (CT) were correlated with functional indexes in patients obliterative bronchiolitis. MATERIALS AND METHODS: Fifteen (all women) who fulfilled the strict criteria for diagnosis bronchiolitis underwent thin-section CT full inspiration and end expiration. The scans scored by two observers extent decreased attenuation lung parenchyma; end-expiration signs air trapping; bronchial dilation, wall thickening, mucous plugging. importance each sign was evaluated. RESULTS: Areas present all (median score expiration, 61%; range, 21%-83%). Bronchial thickening identified 13 15 patients. Correlations measures air-flow obstruction strongest between expiration flow low volumes (r(s) =...
