Abstract

129Xe magnetic resonance imaging in a magnetic field of 4.7 T and at 311 K with laser polarization in the same field is reported. In order to overcome the self-diffusion effect that destroys the transverse magnetization very rapidly, gradient echo is used instead of spin echo. Spectroscopic image is also obtained. Two-dimensional spin nutation spectroscopy under steady state was used to calibrate π/2 pulse of 129Xe in gaseous state. In addition, we have measured the relaxation time of laser-polarized gaseous 129Xe using the saturation-recovery method.
