Abstract :Chronic Obstructive Pulmonary Disease insert ignore into journalissuearticles values(COPD); is diagnosed with pulmonary function tests insert ignore into journalissuearticles values(PFTs);. However, since not all patients can be diagnosed with PFTs, some are diagnosed with radiological or clinical findings. The purpose of this study was to define the properties of obstructive airway disease through thoracic computed tomography insert ignore into journalissuearticles values(CT); and to identify the diagnostic efficacy of CT findings. A total of 160 patients who underwent PFT and thoracic CT assessment July 2018 - January 2019, were retrospectively analyzed. Based on PFT findings, patients were categorized into three groups as having normal, restrictive or obstructive airways. Age, height, weight, and body mass indexes of the groups were recorded. Pulmonary height, width, right-left hemi-diaphragm height, sterno-diaphragmatic angle and retrosternal transparent area length in axial sections were also recorded. Diagnostic efficacies of these parameters in the detection of obstructive airway disease were measured. Of the 160 patients insert ignore into journalissuearticles values(109 males, 51 females; mean age = 59.5);, 91 insert ignore into journalissuearticles values(56.9); had normal PFT, 58 insert ignore into journalissuearticles values(36.2%); had obstructive and 11 insert ignore into journalissuearticles values(6.9%); had restrictive airway disease. Pulmonary height, width, sterno-diaphragmatic angle, and retrosternal transparent area length were significantly higher in patients with obstructive airway disease while the right-left hemi-diaphragm height was significantly lower insert ignore into journalissuearticles values(p<0.001);. About 60-75% sensitivity and specificity were obtained when identifying the obstructive airway disease with these parameters. These values obtained from the axial and sagittal sections could contribute to the diagnosis of obstructive airway disease.
