We have recently developed new software to obtain longitudinal images and accurate short
axis images of airways with an inner diameter> 2 mm located anywhere in the lung, using …

Rationale: Chronic obstructive pulmonary disease (COPD) is characterized by airflow
limitation caused by emphysema and/or airway narrowing. Computed tomography has been …

Background Although airway luminal area (Ai) is affected by lung volume (LV), how is not
precisely understood. We hypothesized that the effect of LV on Ai would differ by airway …

Background and objective: COPD and bronchial asthma are chronic airway diseases with a
different pathogenesis. Comparisons of differences in airway calibre by bronchial generation …

Purpose: To analyze the relationship between airflow limitation and airway dimensions from
the third to the fifth generation of bronchi in patients with chronic obstructive pulmonary …

Background: Chronic obstructive pulmonary disease (COPD) is characterized by airflow
obstruction caused by emphysema or airway narrowing, or both. Recently airway …

Three-dimensional airway analysis, using high-resolution computed tomography (CT), has
only recently become a reality for studying airway dimensions and remodeling in chronic …

Objective The aim of this study was to evaluate the relationship between computed
tomography assessed lobe-based lung parameters and the clinical outcomes of patients …

Background The purpose of this study was to examine changes in the airway lumen and
parenchyma in relation to lung function in patients with chronic obstructive pulmonary …

Background Decreased airway lumen size and increased lung volume are major structural
changes in chronic obstructive pulmonary disease (COPD). However, even though the outer …
