T2* mapping has previously been investigated in cardiac imaging for iron overload assessment and detection of myocardial BOLD effects. Advanced T2* measurement techniques have been previously demonstrated with chemical shift-based fat-water separation techniques in applications such as iron- and fat-content measurement in the liver, and chemical shift-based fat-water decomposition methods have been used to separate fat and water in cardiac imaging. In this work, the feasibility of T2* mapping with chemical shift-based fat-water decomposition in cardiac imaging is demonstrated.
