Detailed Description
MR images of the lung obtained using HP 3He, HP 129Xe, and inert fluorinated gases essentially show the distribution of the inhaled gas inside the lungs. Measurements can be performed on these images to provide additional information that can be related to pulmonary function.
Participation will involve at least two study visits. During the first visit, participants will provide written, informed consent, and undergo eligibility screening. Study drug administration, use of the investigational devices, and MR imaging for this study will be performed at the 3T Research MRI at the Thunder Bay Regional Health Sciences Centre (TBRHSC). Pulmonary Function Tests (PFTs) will be performed at TBRHSC by a Registered Respiratory Therapist (RRT) and an MR Tech will be present for the duration of participant scans.
Participants will be placed in the MRI with the appropriate chest coil wrapped around them like a vest. Several inhalation procedures will be carried out during scanning. Participants safety will be closely monitored throughout the entire study.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Healthy Participants
Participants will inhale investigational gases (HP 3He, HP 129Xe, PFP and SF6) according to the procedure for that intervention.
All participants can potentially inhale all the gases.
Magnetic resonance imaging will be performed during breath-holds or continuous breathing (gas-dependent) with the appropriate investigational human lung coil (3He Human Lung Coil, 129Xe Small and Large Human Lung Coil, or PFP and SF6 Human Lung Coil), using the 3T Research MRI at the Thunder Bay Regional Health Sciences Centre.
|
3He will be hyperpolarized using a custom-built polarizer to enhance its MRI signal.
Hyperpolarization does not change the chemical or physical properties of helium gas.
Other Names:
129Xe will be hyperpolarized using a Xemed polarizer to enhance its MRI signal.
Hyperpolarization does not change the chemical or physical properties of xenon gas.
Other Names:
Perfluoropropane (PFP) will be premixed and delivered to the participants with no further processing.
Other Names:
Sulfur hexafluoride (SF6) will be premixed and delivered to the participant with no further processing.
Other Names:
The investigational 129Xe small and large quadrature lung coils are sensitive to 129Xe resonant frequencies and therefore will be paired with the investigational drug 129Xe.
The size of the coil used will depend on the participants' body size.
The investigational 3He quadrature lung coil is sensitive to 3He resonant frequencies and therefore will be paired with the investigational drug 3He.
The investigational PFP and SF6 quadrature lung coil is sensitive to inert fluorinated gas resonant frequencies and therefore will be paired with both PFP and SF6.
