In this study, the feasibility of using B1 gradients in detecting the shear properties of tissues at kilohertz range frequencies is shown. With this method, shear waves on stiff and small tissues can be detected with high resolution without frequency limitation faced up with in methods using B0 gradient coils due to the slow gradient switching times.
