Abstract:Anatomy-based quantification of emphysema in a lung screening cohort has the potential to improve lung cancer risk stratification and risk communication. Segmenting lung lobes is an essential step in this analysis, but leading lobe segmentation algorithms have not been validated for lung screening computed tomography (CT).Approach: In this work, we develop an automated approach to lobar emphysema quantification and study its association with lung cancer incidence. We combine selfsupervised training with level … Show more
