Conditions
Summary
The purpose of this study is to develop and evaluate the usefulness of MRI using 129Xe gas for regional assessment of pulmonary function. Specifically, three forms of 129Xe MRI contrast will be the investigators focus - 1) imaging of the 129Xe ventilation distribution, 2) imaging the alveolar microstructure via the 129Xe apparent diffusion coefficient (ADC), and 3) imaging 129Xe that dissolves in the pulmonary blood and tissues upon inhalation. Such imaging of 129Xe gas transfer is expected to be uniquely sensitive to pathologies affecting gas exchange (fibrosis, emphysema, pulmonary hypertension) and provide new insights regarding the normal resting heterogeneity of pulmonary gas exchange.

Interventions
Hyperpolarized 129Xenon Gas will be administered in multiple doses in volumes that are tailored to the subject's total lung capacity (TLC) followed by a breath hold of up to 15 seconds. Subsequent 129Xe doses will only be administered once the subject is ready to proceed.
