Volumetric Patch-Based Super-Resolution Reconstruction of Hyperpolarized ¹³C Cardiac MRI.

ABSTRACT: The achievable spatial resolution of ¹³C metabolic images acquired with hyperpolarized ¹³C-pyruvate is worse than ¹H images typically by an order of magnitude due to the rapidly decaying hyperpolarized signals and the low gyromagnetic ratio of ¹³C. This study is to develop and characterize a volumetric patch-based super-resolution reconstruction algorithm that enhances spatial resolution ¹³C cardiac MRI by utilizing structural information from ¹H MRI. The reconstruction procedure comprises anatomical segmentation from high-resolution ¹H MRI, calculation of a patch-based weight matrix, and iterative reconstruction of high-resolution multi-slice ¹³C MRI. The method was tested with a multi-compartmental di
