## Abstract MR imaging of hyperpolarized (HP) nuclei is challenging because they are typically delivered in a single dose of nonrenewable magnetization, from which the entire image must be derived. This problem can be overcome with HP ^129^Xe, which can be produced sufficiently rapidly to deliver i
We describe an experimental approach that combines multidimensional NMR experiments with a steadily renewed source of laser-polarized 129 Xe. Using a continuous flow system to circulate the gas mixture, gas phase NMR signals of laser-polarized 129 Xe can be observed with an enhancement of three to f
## Abstract Using a new method of xenon laserβpolarization that permits the generation of liter quantities of hyperpolarized ^129^Xe gas, the first ^129^Xe imaging results from the human chest and the first ^129^Xe spectroscopy results from the human chest and head have been obtained. With polariza
