Laser-polarized 129 Xe dissolved in a foam preparation of fresh in blood found 4.5 { 1 s in red blood cells and 9 { 2 s in human blood was investigated. The NMR signal of 129 Xe dissolved plasma (18). This experiment used thermally polarized 129 Xe in blood was enhanced by creating a foam in which t

Laser-polarized (129)Xe and a high-T(c)superconducting quantum interference device (SQUID) are used to obtain magnetic resonance images in porous materials at a magnetic field of 2.3 mT, corresponding to a Larmor frequency of 27 kHz. Image resolution of 1 mm is obtained with gradients of only 1 mT/m
Size dependency of the relaxation time T 1 was measured for laserpolarized 129 Xe gas encapsulated in different sized cavities made by glass bulbs or gelatin capsules. The use of laser-polarized gas enhances the sensitivity a great deal, making it possible to measure the longer 129 Xe relaxation tim
