Here we introduce a new pulse sequence, Diffusion-MRE (dMRE),
for concurrent MRE and diffusion MRI. In dMRE shear
motion and diffusion attenuation are encoded into the MR
phase and magnitude by using a pair of bipolar
gradients. The sequence timing is adjusted so that the
bipolar gradients are sensitive to both coherent and
incoherent intravoxel motion. The phantom results showed
that simultaneous MRE and diffusion acquisition is
feasible with no interference between MRE/diffusion
acquisitions. The dMRE method may play a role in
improving the use of MRE and diffusion for the detection
of the diseases in liver and brain.
