Abstract The purpose of this study was to evaluate the recently proposed technique of 3 He 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 cooled to 2.4 K in a magnetic field of 8 Tesla to obtain a polarization of 0.26%. The polarized 3 He was warmed up to room temperature and transferred to a rat, with a final polarization of about 0.1%, large enough for acquiring a 3D image of the rat lung in 30 s.
