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.
