Hyperpolarised 129Xe dissolves into various biological tissues and has a change in resonance frequency that is sensitive to its environment. The resonance frequency has previously been shown to be sensitive to red blood cell oxygen saturation and its use as an exogenous probe for MR oximetry is of interest. Here, we develop we develop a robust, quantitative relationship between oxygen saturation and chemical shift in vitro.
