Has anyone had or heard of an MRE? The article below is from Mayo.
I and probably many of us with long standing TOS suffer from myofascial pain as part of or in addition to TOS. Is hypertrophy considered muscle hardening and loss of elasticity?

"...magnetic resonance elastography, or MRE, can provide images of the affected muscle with clarity and insight not possible with magnetic resonance imaging, or MRI. While an MRI uses a magnetic field and radio waves to create clear and detailed cross-sectional images of the body's internal tissues and organs, an MRE measures the elasticity of tissue as it is gently vibrated.

"Additional research is necessary, but our findings in this pilot study provide a strong basis to suspect that MRE technology can identify changes in muscle tone and stiffness that could previously only be identified by physical examination by a physician or a therapist," says Jeffrey Basford, M.D., Ph.D., a Mayo Clinic specialist in physical medicine and rehabilitation and an author of the study. "Prior to these findings, we did not have a good diagnostic test for myofascial pain syndrome."

An MRE employs standard MRI equipment with a few modifications, and works by measuring the wavelength of vibrations sent through the tissues. A vibrating metal plate is placed on the patient causing muscles to contract and stiffen. When this occurs, researchers can measure the elasticity of muscles and detect abnormal hardening of tissues, which in myofasical pain syndrome can cause pain. "
