A single-shot echo-planar imaging (EPI) cardiac MRE technique is introduced which provides harmonic displacement images of the heart within 20 to 70 ms acquisition time depending on the desired motion sensitivity and image resolution. This method allows one to study multiple effects of wave dynamics in confined media with time-varying elastic and geometrical properties. Single-shot EPI-MRE facilitates time-resolved evaluation of wave amplitudes as a possible marker for myocardial dysfunction.
