Metabolic imaging with hyperpolarized [1-13C]pyruvate has high potential for examination of myocardial viability. In this work a 3D cardiac sequence for imaging the metabolism of hyperpolarized [1-13C]pyruvate over the whole porcine heart is presented. Therefore a multiband pulse was implemented using the polarization very efficiently. The results demonstrate, that the presented acquisition scheme is feasible for [1-13C]pyruvate metabolic imaging by accurately depicting pyruvate lactate and bicarbonate distributions over the entire left ventricle.
