## 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

## 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
## Abstract Hyperpolarized ^129^Xe has been used to obtain gas phase images of mouse lung __in vivo__, showing distinct ventilation variation as a function of the breathing cycle. Spectra of ^129^Xe in the thorax show complex structure in both the gas phase (β4 to 3 ppm) and tissueβdissolved (190β2
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
The demonstration of MR images using hyperpolarized cylindrical 25 cm 3 Pyrex polarization cell of 2 cm diameter 129 Xe has introduced a potential new contrast modality for and 7 cm length was coated with octadecyltrichlorosilane imaging (1, 2). Recently, others obtained hyperpolarized (OTS) (11) to
