Rationale Bronchodilator responsiveness (BDR) is a common but variable phenomenon in
COPD. The CT characteristics of airway dimensions that differentiate COPD subjects with …

Background Small airway remodeling is the cardinal feature underlying chronic airway
diseases. There is no modality which identifies small airway pathological changes, which is …

Methods Twenty-four patients with stable asthma and 11 individuals without asthma were
studied. EBUS was performed with a radial 20-MHz ultrasonic probe inserted into the …

Background Chronic obstructive pulmonary disease (COPD) is characterized by airflow
limitation caused by emphysema and small airway narrowing. Quantitative evaluation of …

Airway wall thickening in cigarette smokers is thought to be a result of inflammatory changes
and airway remodeling. This study investigates if CT-derived airway wall thickening …

BACKGROUND: Bronchial dimensions measured in CT images generally do not take
inspiration level into consideration. However, some studies showed that the bronchial …

This study measured the accuracy of our airway quantification scheme using phantoms
airway under different CT protocols. Airway remodeling is associated with several thoracic …

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 …

In this issue of the European Respiratory Journal, VIGNOLA et al.[1] report an association
between high-resolution computed tomography (HRCT) scan abnormalities of the …

Purpose With the help of quantitative computed tomography (QCT), it is possible to identify
smoking-associated airway remodeling. However, there is currently little information on …
