    1. Gender Differences in Airway Wall Measurements with Optical Coherence Tomography (OCT).

      Purpose: To examine the difference in the relationship between airway wall dimensions and lung function in male and female smokers. Methods: 35 male and 18 female subjects from the BC Lung Health Cohort, who underwent OCT imaging and spirometry, were studied. OCT images, acquired at the time of bronchoscopy, were converted to digital images at 0.5s intervals using frame capture software. Airways were measured using ImageJ (NIH) image analysis software on 5 consecutive frames when the airway attained the diameter of the OCT probe (1.5mm) Lung function, represented by FEV1% predicted, was plotted against the wall area percent ...

    2. Inter- and Intra-Observer Variability in Measurements of Airways Using Optical Coherence Tomography (OCT).

      Purpose: To devise a protocol for the measurement of airways using optical coherence tomography (OCT) with acceptable inter− and intra−observer variability. Methods: 59 subjects from the British Columbia Lung Health Cohort who underwent OCT imaging were studied. OCT images, acquired at the time of bronchoscopy were converted to digital images at 0.5s intervals using frame capture software. Airways were measured using ImageJ (NIH) image analysis software on 5 consecutive frames when the probe was located in an airway with the same diameter as the probe (1.5mm). The airway lumen and wall areas were measured using the circular ...
