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.
