One of the earliest hp ¹²⁹Xe spectra and washout dynamics from the rat pulmonary system. (a) Hp ¹²⁹Xe spectra at t = 0 after inhalation of the last xenon bolus. Peak A, B and C at 191, 199, 213 ppm relative to the gas phase peak at 0 ppm attributed to the blood plasma, lung tissue and red blood cells respectively. (b) Temporal dynamics on hp ¹²⁹Xe washout with the combined effects of ventilation, RF depletion and longitudinal relaxation. Reprinted with permission from Sakai et al. J. Magn. Reson. Ser.
