Sternum drivers for breast MRE can produce shear waves in breasts without breast compression effect, which can result in increased breast stiffness due to tissue nonlinearity. A recent 5-slice 2D GREMRE sequence study found sternum driver MRE was a very reproducible method. In our current study, we were able to use 40-slice 3D GREMRE volumetric MRE sequence to compute volumetric breast elastograms in patients.
