Here we introduce a recipe for the simultaneous
acquisition of Diffusion tensor imaging (DTI) and
3D-vector field MR Elastography (MRE) data. The
simultaneous encoding of MRE and diffusion is first
achieved by modulating the timing of the
motion-sensitizing gradient with the diffusion time, and
with the mechanical vibration frequency. The
simultaneous acquisition of a 3D-vector field MRE and
DTI is then achieved by designing a particular gradient
encoding scheme with the application of a series of
motion-sensitizing gradients in non-collinear and
non-coplanar directions. The present work demonstrates
the feasibility of the proposed concept in the mouse
brain in vivo.
