AbstractMeasurement of tumor oxygenation has gained importance in the last decades due to the known relationship between tumor hypoxia and tumor aggressiveness, poor outcome and resistance to therapies. Several techniques have been developed for this end (oxygen electrodes, EPR, PET…) but none of them has gained widespread acceptance. 2-Nitroimidazole derivatives (EF5, Pimonidzole, 18F-MISO...) have been extensively used as molecular markers of hypoxia in combination with different techniques as immunohistochemistry, PET or 19F-MRI. Here we evaluate, for the first time to our knowledge, the use of these hypoxia markers in combination with 1H-MRSI to generate oxygenation maps in vivo.
