Keywords: Data Processing, CardiomyopathyThe volumetric patch-based super-resolution method can reconstruct a single-slice low-resolution hyperpolarized 13C MRI to multiple 13C slices with enhanced spatial resolution by exploiting the corresponding high-resolution structural 1H MRI. In this study, the overall performance of this method and the effects of patch size were evaluated using a simulated digital phantom and an anthropomorphic cardiac 13C MR phantom. The optimal patch size for this reconstruction method was also applied to in-vivo human 13C cardiac images acquired with an injection of hyperpolarized [1-13C]pyruvate.
