There is attractive focus in developing non-invasive methods that assess tumor hypoxia. We applied tissue oxygen level dependent (TOLD) MRI to explore tumor oxygenation using VX2 liver tumor xenografts in a rabbit model. In this study,we demonstrated alteration in tumor oxygen inhalation and correlation in different hypoxia levels.
