Metabolic imaging with hyperpolarized [1-<sup>13</sup>C] pyruvate in patient-derived preclinical mouse models of breast cancer.
MetadataShow full item record
<sup>13</sup>C nuclear spin hyperpolarization can increase the sensitivity of detection in an MRI experiment by more than 10,000-fold. <sup>13</sup>C magnetic resonance spectroscopic imaging (MRSI) of hyperpolarized <sup>13</sup>C label exchange between injected [1-<sup>13</sup>C]pyruvate and the endogenous tumor lactate pool can be used clinically to assess tumor grade and response to treatment. We describe here an experimental protocol for using this technique in patient-derived and established cell line xenograft models of breast cancer in the mouse. For complete details on the use and execution of this protocol, please refer to Ros et al. (2020).
