Evaluation and Immunohistochemical Qualification of Carbogen-Induced ΔR2* as a Noninvasive Imaging Biomarker of Improved Tumor Oxygenation

The combined use of intrinsic susceptibility magnetic resonance imaging with a double hypoxia marker approach corroborates carbogen-induced ΔR2* as a noninvasive imaging biomarker of increased tumor oxygenation.
