To design and validate a rapid, single breath-hold 3D volumetric GRE-MRE
sequence that is capable of estimating viscoelastic tissue properties in the
liver.
Figure 4: Shear
velocity map in the abdomen for volunteer 1. The shear velocity values are
acquired with Intenso,
averaged over the four inner-most slices and matched with the abdominal anatomy
(e.g. liver, spleen and spine are highlighted).
Figure 5: Elasticity
and viscosity maps (KPa) in the abdomen for volunteer 1, and one component of
the curl of the displacement field is shown as well. The maps were
acquired with Intenso,
and the viscoelastic values are averaged over the four inner-most slices. The
viscoelastic maps are matching with the abdominal anatomy (e.g. liver, spleen
and spine are highlighted).
