This study applied a dual-agent, 13C-pyruvate and 13C-urea, hyperpolarized 13C magnetic resonance spectroscopic imaging (MRSI) and multi-parametric (mp) 1H magnetic resonance imaging (MRI) approach in the transgenic adenocarcinoma of mouse prostate (TRAMP) model to investigate changes in tumor perfusion and lactate metabolism during prostate cancer development, progression and metastases, and after lactate dehydrogenase-A (LDHA) knock-out. This evidence concerns the gene LDHA and adenocarcinoma.
