Chemical shift based water-fat separation methods have recently been demonstrated for 1.5T cardiac imaging. Higher field strengths (most notably 3T) are increasingly used in cardiac imaging, but water-fat separation techniques can be challenging due to proportionately higher resonance frequency offsets. An interleaved multi-echo sequence using the IDEAL water-fat method has been developed for cardiac imaging at 3T and applied to the evaluation of delayed-enhancement imaging and other fat-containing pathologies.
