Researchers at the Mayo Clinic in Rochester, Minn., have been working with magnetic resonance elastography (MRE), a medical imaging technique developed to non-invasively diagnose and monitor disease. The device they use, MR-Touch, uses low-frequency sound waves for just 15 seconds at the tail end of a typical MRI procedure to measure tissue elasticity. It is essentially touching the tissue through vibration instead of surgery. This could help better monitor disease progression and provide more informed preventative guidance, and kudos for making such a procedure non-invasive, much to the relief of an already beleaguered patient who has been poked and prodded all over the place.
