Previous studies have shown that cardiac CEST technique can detect myocardial metabolic abnormalities in chronic myocardial infarction. However, this navigator-gated technique is still sensitive to B0 field variations caused by respiratory motion within the acceptance window.

In this work, we developed a cardiac CEST dual-echo technique which not only acquires CEST-weighted image, but also enables acquisition of B0 map for each saturation frequency offset. The reproducibility of this technique was also assessed.
