“Xenon-129 Magnetic Resonance Imaging of Healthy Subjects: Hardware and Software Development and Reproducibility”
Healthy volunteers aged 18-85 will undergo hyperpolarized 129-Xe MRI and pulmonary function testing for the development of tools to assess image signal to noise and reproducibility of spin-density and diffusion-weighted imaging.

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 ...read more on ClinicalTrials.org
