129 Xenon MRI in Chronic Lung Disease
Sponsor: Western University, Canada
Summary
Subjects aged 18-85 with lung disease will undergo hyperpolarized Xenon 129 (129-Xe) MRI and Pulmonary Function testing for the development of tools to evaluate the Apparent Diffusion Coefficient (ADC), ventilation defect percent (VDP) and pulmonary gas exchange measurements obtained by analysis of hyperpolarized 129-Xe MRI.

Hyperpolarized Xenon MRI
Hyperpolarized noble gas imaging using Xenon-129 has been used to explore structural and functional relationships in the lung in patients with lung disease and healthy controls. In contrast to proton-based MRI imaging, 129Xe gas is used as a contrast agent to directly visualize the airways, and thus ventilation. Whereas the normal density of gas is too low to produce an easily detectable signal, this is overcome by artificially increasing the amount of polarization per unit volume using optical pumping.
