The extent of pulmonary emphysema is commonly estimated from CT scans by computing
the proportional area of voxels below a predefined attenuation threshold. However, the …

Determining the extent of pulmonary emphysema with quantitative computed tomography
commonly relies on fixed intensity threshold values. However, the reliability of such …

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 …

RATIONALE AND OBJECTIVES: The aim of this study was to present and evaluate a fully
automated system for emphysema quantification on low-dose computed tomographic …

Background CT scan has notable potential to quantify the severity and progression of
emphysema in patients. Such quantification should ideally reflect the true attributes and …

This article investigates the suitability of local intensity distributions to analyze six
emphysema classes in 342 CT scans obtained from 16 sites hosting scanners by 3 vendors …

We aim at improving quantitative measures of emphysema in computed tomography (CT)
images of the lungs. Current standard measures, such as the relative area of emphysema …

Quantitative assessment of emphysema in CT scans has mostly focused on calculating the
percentage of lung tissue that is deemed abnormal based on a density thresholding …

Emphysema is one of the most widespread diseases in subjects with smoking history. The
gold standard method for estimating the severity of emphysema is a lung function test, such …

OBJECTIVE. Emphysema is a disease of the lung characterized by the destruction of the
alveolar sac walls. Several quantitative densitometric measures of emphysema from …
