¹²⁹Xe spectrum obtained by summing the 7th through 12th scans of an injected xenon/Intralipid solution. The xenon/Intralipid solution was injected intravenously in the tail, and signal was acquired with a surface coil localized over the liver region. The chemical shift range is referenced to a polarized xenon gas sample (pressure ≈ 5 atm) scanned prior to experiment; the chemical shift is consistent with xenon residing in Intralipid once the reference pressure has been considered (19). (Inset) Time dependence of the integrated xenon signal in the liver region.
