    Elastic Properties of the Central Airways in Obstructive Lung Diseases Measured Using Anatomical Optical Coherence Tomography
    Rationale: Our understanding of how airway remodeling affects regional airway elastic properties is limited due to technical difficulties in quantitatively measuring dynamic, in vivo airway dimensions. Such knowledge could help elucidate mechanisms of excessive airway narrowing. Objectives: To utilize anatomical optical coherence tomography (aOCT) to compare central airway elastic properties in control subjects and those with obstructive lung diseases. Methods: Following bronchodilation, airway lumen area (Ai) was measured using aOCT during bronchoscopy in control subjects (n=10) and those with asthma (n=16), chronic obstructive pulmonary disease (COPD) (n=9) and bronchiectasis (n=8). Ai was measured in each of ...
