In treated asthmatics, symptom scores better correlate with airway geometry than with Fev1 Ghent University
Asthma treatment can be guided by clinical symptoms, eNO and lung function. Recently it became possible to measure changes in airway caliber by performing airway segmentations starting from CT images (J. Biomech 2008;41:106-113). The aim of this study was to see how changes in airway caliber (imaged airway volume, iVaw) correlate with symptoms, eNO and spirometry. We studied 7 steroid naïve patients [2 M, 5F; age 51.8(8.7)y] before and after 6 ...
