MR Elastography is a technique to evaluate the biomechanical properties of soft tissues noninvasively. Its application in the heart is very challenging due to several factors including actuator hardware, robust MR sequences, and suitable reconstruction strategies. One of the biggest limitations for data acquisition of cardiac MRE scans is the breath hold duration which is up to 21 heart beats, repeated several times for a full dataset. The main goal of this study was the implementation of an MR sequence with simultaneous multi slice acquisition capability to reduce the breath hold duration and increase comfort and compliance for the subjects.
