Differentiation of quantitative CT imaging phenotypes in asthma versus COPD

Abstract excerpt

Introduction: Quantitative CT (QCT) imaging-based metrics have quantified disease alterations in asthma and chronic obstructive pulmonary disease (COPD), respectively. We seek to characterise the similarity and disparity between these groups using QCT-derived airway and parenchymal metrics. Methods: <80%. Healthy non-smokers were included as a control group. Inspiratory and expiratory QCT images of 75 asthmatic,...
