| Research Abstract |
We compared the parameters of area-detector CT to that of respiratory function test to evaluate the obstructive respiratory disorder in COPD patients. The parameters of obstruction(% FEV1. 0, FEV1. 0%, RV,% RV) worsen in COPD patients with high frequency of resonance. The ratio of airway wall thickness to total diameter(T/D ratio) was higher in COPD patients with high frequency of resonance. There was negative correlation between R5-R20and airway internal diameter in6th branch and positive correlation between R5-R20and airway wall area.
