19F-MRI oxygen mapping. Shown are typical oxygen maps obtained using 19F-MRI with hexafluorobenzene as the oxygen sensor in an experimental tumor under air or carbogen (95% O2, 5% CO2) breathing conditions. The corresponding histograms are shown, in which “n” represents the number of voxels for a given oxygen concentration range. Adapted from reference Jordan et al. (2009).
