The purpose of the present study was to develop a cine DENSE sequence with dual displacement encoding, where two distinct stimulated echoes with different displacement-encoding frequencies are simultaneously stored along the longitudinal axis, and where either can be recalled at any particular time to to better accommodate a temporal sequence of images with different amounts of displacement and deformation at different times. The sequence was implemented on a 1.5T scanner and was evaluated and demonstrated by using a deformable phantom and by imaging the hearts of normal volunteers.
