Metabolic imaging of the heart following injection of hyperpolarised pyruvate could allow new methods for diagnosis and characterisation of heart disease. However, fast and efficient imaging sequences are required to adequately encode the information due to the rapidly decaying signal. Therefore, parallel imaging could be highly beneficial for in vivo metabolic imaging to speed up the acquisition process. In this work, an efficient autocalibrated single-shot spiral parallel imaging sequence for metabolic imaging of hyperpolarised compounds is presented. It is demonstrated that parallel imaging enables single-shot dynamic hyperpolarised imaging of the pig heart, which is an important step towards human studies.
