Rationale Airflow obstruction and/or emphysema have been associated with lung cancer
risk; however, this relationship and the joint occurrence of these conditions are not well …

Introduction Computed tomography (CT) and magnetic resonance imaging (MRI) can
provide detailed anatomic structures and quantitative function information for chronic …

Obesity is a common comorbidity of chronic obstructive pulmonary disease (COPD) and has
been associated with worse outcomes. However, it is unknown whether the interaction …

Background: Both emphysematous destruction of lung parenchyma and airway remodeling
is thought to contribute to airflow limitation in cases of chronic obstructive pulmonary disease …

Purpose Emphysema and chronic obstructive lung disease were previously identified as
major risk factors for severe disease progression in COVID-19. Computed tomography (CT) …

Computed tomography (CT) imaging is being increasingly used in clinical practice for
detailed characterization of lung diseases. Respiratory diseases involve various …

Objectives To determine the improvement of emphysema quantification with density
correction and to determine the optimal site to use for air density correction on volumetric …

Depth-based plethysmography (DPG) for the measurement of respiratory parameters is a
mobile and cost-effective alternative to spirometry and body plethysmography. In addition …

Purpose We sought to determine the volume of each anatomic lung lobe reconstructed
using 3-dimensional computed tomography (3D-CT) imaging from multidetector CT images …

Objective To compare CT volume analysis with MR perfusion imaging in differentiating
smokers with normal pulmonary function (controls) from COPD patients. Methods Sixty-two …
