The purposes of this study were: to describe chest CT findings in normal non-smoking
controls and cigarette smokers with and without COPD; to compare the prevalence of CT …

With fabrication technology reaching nanolevels, systems are becoming more prone to
manufacturing defects with higher susceptibility to soft errors. This paper is focused on …

Rationale: A significant proportion of smokers have lung function impairment characterized
by a reduced FEV1 with a preserved FEV1/FVC ratio. These smokers are a poorly …

Purpose To compare measurements of regional pulmonary perfused blood volume (PBV)
and pulmonary blood flow (PBF) obtained with computed tomography (CT) in two pig …

Rationale: Endothelial dysfunction is of interest in relation to smoking-associated
emphysema, a component of chronic obstructive pulmonary disease (COPD). We previously …

Objectives The purposes of this study were to evaluate the reference range of quantitative
computed tomography (QCT) measures of lung attenuation and airway parameter …

Background Imaging variables, including airway diameter, wall thickness, and air trapping,
have been found to be important metrics when differentiating patients with severe asthma …

The lung is both the conduit for oxygen uptake and is also affected by hypoxia and hypoxia
signaling. Decreased ventilatory drive, airway obstructive processes, intra-alveolar …

The term 'emphysema'is generally used in a morphological sense, and therefore imaging
modalities have an important role in diagnosing this disease. In particular, high resolution …

Rationale: Computed tomography (CT)-based lung density is used to quantitate the
percentage of emphysema-like lung (hereafter referred to as percent emphysema), but …
