Quantitative assessment of airway caliber is generally confined to indirect physiologic
methods or to radiographic techniques. Fiberoptic bronchoscopy provides a direct view of …

Background: Quantitative assessment of airway caliber is generally confined to indirect
methods. Fiberoptic bronchoscopy provides a direct view of the airways, but measurement of …

Bronchoscopy is a commonly used clinical tool that provides a direct image of the bronchial
lumen. However, bronchoscopy has seen little use as a quantitative measurement tool …

Bronchoscopic evaluation of stenosis is limited due to radial distortion of bronchoscopic
images and the unknown distance between the endoscope and the stenotic area. The …

Exaggerated airway narrowing in response to bronchoconstricting stimuli is a characteristic
feature of asthmatic subjects. It is unknown whether the site of airway narrowing differs in …

The severity of airway narrowing impacts ventilatory function, quality of life, and choice of
therapy for patients with central airway obstruction. The quantification of airway caliber …

Measurement of airway size using endoscopic morphometry was investigated. Endoscopic
images of the porcine tracheobronchial tree were obtained via a Storz system at a known …

We performed a prospective masked animal study to determine whether virtual
bronchoscopy, a noninvasive computed tomography technique, can accurately measure …

Computed tomography (CT) of the lungs makes it possible to study individual airways. A
technique using high-resolution-CT (HRCT) has been developed to measure the internal …

Background: Accurate measurements of airway and lesion dimensions are important to the
developmental progress of paediatric bronchoscopy. The malacia disorders are an …
