Abstract:
Objective To study the changes with aging of lung density parameters on inspiratory and expiratory HRCT in asymptomatic nonsmokers,and the correlation with pulmonary function test(PFT).Methods Lung HRCT scans were performed at end inspiratory and end expiratory in 63 subjects,and PFT were performed in 32 of them.All the subjects were divided into 5 groups according to the ages.Lung HRCT quantitative parameters of each groups were measured,and the correlation with PFT results was assessed.Results In each age group,the mean lung density of expiratory lung HRCT and the overall lung density difference between inspiratory and expiratory HRCT was significant decrease(P
