Care should be taken
to account for motion between breath-hold acquisitions in magnetic resonance
elastography.
Figure 5: Magnitude
images for
one extreme case for each breath-hold at the highest simulated motion level and
the original magnitude image for reference. The average Dice score over the breath-holds
was 0.58. The elasticity maps before and after motion are also shown.
Figure 4: Violin plots comparing elasticity for all cases within each
region to the ground truth (GT) for
increasing motion. The average Dice overlaps between regions before and after
motion are shown in blue. A table of the bulk motion and deformation applied for each motion level is also shown.
