Magnetic resonance rheology is a novel method to create an imaging contrast based on the mechanical properties of brain tissue. It is based on a short fall of the head that creates a broadband excitation of the tissue. The resulting deflections of the tissue elements are depicted using motion sensitive phase imaging. This contribution presents measurements on agar phantoms as well as four meningioma patients to show the feasibility of the method to depict local alterations of the mechanical properties of the investigated material.
