Definitions of types of emphysema within the framework of chronic obstructive pulmonary
disease are given. The classic findings on the chest radiograph are described, and the …

OBJECTIVE. The purpose of the present study is to prospectively compare the capability of
dynamic oxygen-enhanced MRI and quantitative CT for pulmonary functional loss …

Computed tomographic pulmonary angiography has become the standard of care for the
evaluation of patients with suspected pulmonary embolism (PE). In addition to the direct …

The traditional Hessian-related vessel filters often suffer from detecting complex structures
like bifurcations due to an over-simplified cylindrical model. To solve this problem, we …

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 …

The purpose of the study was to assess pulmonary perfusion on a lobar level in smokers
using dual-energy computed tomography (CT). Forty-seven smokers and ten non-smokers …

Background Histopathological studies on lung specimens from patients with cystic fibrosis
(CF) and recent results from a mouse model indicate that emphysema may contribute to CF …

Using computational fluid dynamics (CFD) method, the feasibility of simulating transient
airflow in a CT‐based airway tree with more than 100 outlets for a whole respiratory period …

To reproduce realistic airway motion and airflow, the authors developed a deforming lung
computational fluid dynamics (CFD) model based on four-dimensional (4D, space and time) …

Parametric response mapping (PRM) of paired CT lung images has been shown to improve
the phenotyping of COPD by allowing for the visualization and quantification of non …
