Improved cardiac sodium MR imaging by density‐weighted phase‐encoding

To show that density‐weighted (DW) k‐space sampling improves the quality of human cardiac sodium imaging, a novel method was implemented that combines the high signal‐to‐noise efficiency of three‐dimensional phase‐encoding with the advantageous localization performance of nonuniform sampling. A simulation demonstrates substantially reduced blood contamination in the myocardium.
