Magnetic Resonance Elastography (MRE) is a technique for measuring the mechanical properties of tissue. This in vivo human study was aimed to evaluate the anisotropic properties of skeletal muscle with an acoustic wave produced by an inserted moving needle, using MRE. The experiments showed that the elasticity of muscle is different when measured parallel and perpendicular to the fibers, confirming that skeletal muscle is mechanically anisotropic, and indicating the feasibility of measuring this independent tissue characterization parameter.
