A noninvasive method to measure the stiffness parameters along fibrous pathways within the brain is helping researchers explore traumatic brain injuries. The stiffness of these tissues can reveal clues about changes and pathologies within the brain’s gray and white matter. During the 179th ASA Meeting, Anthony J. Romano will describe the method known as waveguide elastography. Waveguide elastography merges magnetic resonance elastography and diffusion tensor imaging with a combination of isotropic and anisotropic inversion algorithms.
