## Abstract Hyperpolarized ^129^Xe (HpXe) NMR not only holds promise for functional lung imaging, but for measurements of tissue perfusion as well. To investigate human brain perfusion, several timeβseries of ^129^Xe MR spectra were recorded from one healthy volunteer after HpXe inhalation. The tim

## Abstract The ability to quantify pulmonary diffusing capacity and perfusion using dynamic hyperpolarized ^129^Xe NMR spectroscopy is demonstrated. A model of alveolar gas exchange was developed, which, in conjunction with ^129^Xe NMR, enables quantification of average alveolar wall thickness, pu
## Abstract ## Purpose To apply a continuous flowβtype hyperpolarizing (CFβHP) system to lung imaging and investigate the feasibility of hyperpolarized ^129^Xe MRI at a low xenon concentration. ## Materials and Methods Under two conditions where a 3% or 70% xenon gas mixture was constantly suppl
