Arms of the Study
Arm 1
Arm Type

Arm Label
COPD and Bronchiectasis Patients
Arm Description
All enrolled COPD and Bronchiectasis patients will undergo Pulmonary Function Tests, Hyperpolarized Helium MRI, chest CT, 6-Minute Walk Test, and complete questionnaires at up to 8 visits over 2-3 years.
Outcomes
Primary Outcome Measures
Ventilation Defect Percent (VDP)
VDP is a widely used noble gas MRI biomarkers that is calculated by normalizing ventilation defect volume to the thoracic cavity
Apparent Diffusion Coefficients (ADC)
Diffusion weighted noble gas MRI provides a way to quantify pulmonary microstructure by sensing the movements of inhaled gas atoms. The "apparent" dif fusion coefficient (ADC) during the diffusion time interval can be used to reflect the extent of alveolar restriction of gas atom movements, providing a surrogate measurement of airspace dimensions.
Secondary Outcome Measures
Six Minute Walk Distance (6MWD)
The 6-min walk test (6 MWT) is a submaximal exercise test that entails measurement of distance walked over a span of 6 minutes.
St. George's Respiratory Questionnaire (SGRQ)
Disease-specific instrument designed to measure impact on overall health, daily life, and perceived well-being in patients with obstructive airways disease.
Spirometry
Spirometry is a common office test used to assess how well your lungs work by measuring how much air you inhale, how much you exhale and how quickly you exhale.

5. Study Description
Brief Summary
Subjects male and female aged 50-85 with a clinical diagnosis of chronic obstructive pulmonary disease (COPD) or Bronchiectasis, or those with ≥ 10 pack/years smoking history will be imaged with CT and MRI for the development of tools to quantify and validate longitudinal in vivo magnetic resonance imaging phenotypes of COPD and Bronchiectasis.
Detailed Description
COPD patients will be stratified into four groups: Gold Stage 0, Gold Stage I, Gold Stage II, and Gold Stage III. During a single 2-2 ½ hour visit, patient subjects will perform some or all of: 1) spirometry pre-and-post salbutamol and plethysmography, Lung Clearance Index, Airway Oscillometry (Airwave Oscillometry measures the mechanics of the respiratory system by superimposing a gentle multi-frequency airwave onto the patient's respiratory airflow. Measurements take no longer than 16 seconds and the patient simply breathes normally into a disposable mouthpiece for the duration of the test.) 2) 6MWT (including Borg questionnaire pre-and post-walk), 3) health status evaluation using a self-administered SGRQ and MMRC (Modified Medical Research Council dyspnea scale) 4) CT, and, 5) 3He MRI.
Subjects will first provide written informed consent and then be screened for MRI compatibility and will complete: 1) Spirometry pre-salbutamol, SGRQ after inhaling 2-4 puffs (200-400μg) of the short-acting bronchodilator (eg. Salbutamol), 2) MRI, 3) CT. (Subjects will be taken by wheelchair to and from University Hospital, LHSC to decrease the potential for dynamic hyperinflation), 4) plethysmography and spirometry within 1 ½ hours of salbutamol. Vital signs will be performed. Because it is impossible to schedule imaging at the same time-point post-bronchodilator, subjects will be randomized to MR or CT 30 minutes post-salbutamol (1:1 ratio), to minimize bias.

Intervention Name(s)
Hyperpolarized Helium MRI
Intervention Description
Hyperpolarized helium-3 (3He) magnetic resonance imaging (MRI) has recently emerged as another research approach for the non-invasive measurement of lung structure and function, including conduction of gas through airways and into airspaces. Preliminary studies suggest that 3He MRI may be ideally suited for longitudinal COPD research, which is a likely target application of this novel technology. 3He MRI provides a complementary and alternative method for evaluating COPD and may be superior to CT because it allows simultaneous visualization of both airway and airspace structure and function.
