Rationale
The purpose of this study is to evaluate whether quantitative CT (QCT) measures of emphysema (EMP) and gas trapping (GT) are significantly different when evaluated on images reconstructed with differing “soft” convolution kernels, and to evaluate whether one kernel correlates better with physiology.
