Abstract
The purpose of this study was to evaluate the recently proposed technique o f He-3 prepolarization at low temperature and high field (Kober et al. Magn Reson Med 1999; 41:1084-1087) for fast imaging of the lung. Helium-3 was c ooled to 2.4 K in a magnetic field of 8 Tesla to obtain a polarization of 0 .26%, The polarized He-3 was warmed up to room temperature and transferred to a rat, with a final polarization of about 0.1%, large enough for acquiri ng a 3D image of the rat lung in 30 s.
