  By decoupling motion and spatial encoding, magnitude contrast MR Elastography
could be performed for the first time at ultrashort echo times (12 $\mu$s). On
the basis of a motion-sensitizing magnetization preparation, the available
total magnetic moment is sensitized to the motion induced in the tissues so the
information can be efficiently carried over by the MR signal magnitude when the
selected imaging pulse sequence is applied. The new paradigm allows also for
shorter total acquisition times as demonstrated here in a set of homogeneous
and heterogeneous phantoms with up to 5-fold acceleration factors. Summary of
Main Findings/Short Synopsis Magnitude contrast MR Elastography was developed
on the basis of a motionsensitizing magnetization preparation to subsequently
make use of any type of imaging sequence, like UTE or ZTE, to mechanically
characterize tissues, otherwise inaccessible with standard MRE.
