HCsf MRE sensitivity results for both shear stiffness (μ) and damping ratio (ξ), quantified by minimum difference and variance between subfields for each NLI parameter combination of SPR weighting and SF width

	Stiffness				Damping ratio
SPR	10 −10	10 −12	10 −10	10 −12	10 −10	10 −12	10 −10	10 −12
SF (mm)	1.5	1.5	0.9	0.9	1.5	1.5	0.9	0.9
MD mean	0.037	0.042	0.069	0.071	0.009	0.009	0.012	0.012
MD SD	0.027	0.027	0.088	0.055	0.006	0.006	0.010	0.011
SV mean	0.023	0.027	0.077	0.081	0.0008	0.0011	0.0010	0.0015
SV SD	0.018	0.019	0.088	0.067	0.0006	0.0008	0.0011	0.0016

Note: SPR, soft prior regularization weighting; SF, spatial filtering width (mm); MD, minimum difference; SV, sample variance; SD, standard deviation.
