Limits on the contrast of strain concentrations in elastography.
Using an analytic solution of the elasticity equation derived for a cylindrical inclusion, it is shown that the contrast of the strain concentrations is limited for both hard and soft lesions. This means that, beyond a given elastic modulus contrast, the strain concentrations remain virtually constant.
