Single-shot spin-echo EPI (SS-SE-EPI) has been utilized for cardiac MR Elastography (cMRE) due to its fast imaging speed and insensitivity to cardiac motion. However, the long echo train in SS-EPI makes it vulnerable to image distortion, which can be prominent in cMRE due to the large susceptibility gradient present at the heart-lung interface. In this study, a reduced phase FOV (rFOV) technique combined with a 2D selective excitation has been implemented in the cMRE. And the results showed that the MRE image quality was improved with reduced image distortions and higher SNR.
