About this study

Most individuals with asthma can effectively manage their symptoms and maintain normal lung function using inhaled medications, unfortunately, there is a subset of asthma sufferers whose symptoms, lung function, and risk of asthma attacks remain unimproved despite conventional inhaled medications. There could be several reasons for this. One possibility is that inhaled medications fail to reach the intended areas within the lungs, due to structural abnormalities within the airways themselves. Much like road conditions or closures can impede the speed and efficiency of vehicle travel, factors such as airway narrowing or mucus blockages, which are common in asthma, can obstruct the passage of inhaled medications through the airways. Our team has now optimized advanced medical imaging techniques, including magnetic resonance imaging (MRI) and computed tomography (CT), required to investigate this. This study will use these imaging methods to visually assess and measure individual patients' airways and determine whether abnormal airway structures impact how well they respond to inhaled and orally delivered medications. We anticipate finding that abnormal airway structures make inhaled medications less effective, but that they do not affect the response to oral medications.
