Purpose: To compare high-resolution computed tomography (HRCT) of lungs with pulmo-
nary function in smokers diagnosed with emphysema.
Material and Method: The authors retrospectively reviewed 17 patients with a history of
smoking and dyspnea, who underwent HRCT of the lungs and pulmonary function testing. HRCT
scores were determined and compared to pulmonary function (FEV1, FEV1/FVC, and DLCO).
Results: The HRCT of all 17 patients (17117; 100%) were typical of centrilobular emphy-
sema; with a mean score of 12.88เธ‘9.18 (range, 4 to 34). Decreased FEV1 (
