This study reports the clinical translation of a hybrid-shot spiral sequence (HYSS) for imaging the diseased heart and spleen. Two subjects with myocardial infarction from coronary artery disease were imaged following administration of hyperpolarized [1-¹³C]pyruvate. High lactate and bicarbonate signal were seen in the region adjacent to the infarcted zone, with no signal within the infarct. A large splenic lactate signal was observed in a subject with an active systemic inflammatory response post myocardial infarction.
