Emphysema Quantification on Cardiac CT Scans Using Hidden Markov Measure Field Model: The MESA Lung Study
Cardiac computed tomography (CT) scans include approximately 2/3 of the lung and can be obtained with low radiation exposure. Large cohorts of population-based research studies reported high correlations of emphysema quantification between full-lung (FL) and cardiac CT scans, using thresholding-based measurements. This work extends a hidden Markov measure field (HMMF) model-based segmentation m...
متن کاملOriginal Contribution Association of Environmental Tobacco Smoke Exposure in Childhood With Early Emphysema in Adulthood Among Nonsmokers The MESA-Lung Study
Mechanical stress to alveolar walls may cause progressive damage after an early-life insult such as exposure to environmental tobacco smoke (ETS). This hypothesis was examined by using data from the Multi-Ethnic Study of Atherosclerosis (MESA), a population-based cohort aged 45–84 years, free of clinical cardiovascular disease, recruited from 6 US sites in 2000–2002. The MESA-Lung Study assesse...
متن کاملAir Pollution and Percent Emphysema Identified by Computed Tomography in the Multi-Ethnic Study of Atherosclerosis
BACKGROUND Air pollution is linked to low lung function and to respiratory events, yet little is known of associations with lung structure. OBJECTIVES We examined associations of particulate matter (PM2.5, PM10) and nitrogen oxides (NOx) with percent emphysema-like lung on computed tomography (CT). METHODS The Multi-Ethnic Study of Atherosclerosis (MESA) recruited participants (45-84 years ...

متن کاملExplaining Radiological Emphysema Subtypes with Unsupervised Texture Prototypes: MESA COPD Study
Pulmonary emphysema is traditionally subcategorized into three subtypes, which have distinct radiological appearances on computed tomography (CT) and can help with the diagnosis of chronic obstructive pulmonary disease (COPD). Automated texture-based quantification of emphysema subtypes has been successfully implemented via supervised learning of these three emphysema subtypes. In this work, we...
