Abstract
We sought to determine the volume of each anatomic lung lobe reconstructed using paired inspiratory and expiratory three-dimensional CT (3D-CT) imaging and compare these to pulmonary function test results for 20 COPD patients. The combination of inspiratory and expiratory 3D-CT improved correlation coefficients between forced expiratory volume 1.0 (FEV 1.0) and 3D-CT index. In addition, pulmonary function results were primarily affected by the normal lobar volumes of the lower lobes.
