Magnetic resonance elastography (MRE) is a non-invasive imaging technique that can be used to quantify the mechanical properties of brain tissue. Mechanical changes in brain tissue cannot be directly assessed with conventional imaging, whereas MRE provides viscoelastic maps that reveal stiffness differences between healthy brain tissue and benign and malignant tumors....

Discussion
Signed responses from readers of the wire.
No actionable change for audiology practice; this review concerns brain tumor imaging technology and has no direct clinical implication for audiologists or hearing specialists.
While outside core audiology practice, MR elastography could in future provide non-invasive mechanical characterisation of auditory pathway tumours (e.g., vestibular schwannomas), making this technique worth monitoring.
- 01Magnetic resonance elastography (MRE) non-invasively measures the stiffness of brain tissue.
- 02Review focuses on MRE applications for characterising brain tumor mechanical properties.
- 03MRE may help differentiate tumor types and grades without biopsy.
- 04No direct audiology application is described in this article.
- 05Potential future relevance exists for imaging of acoustic neuromas or other skull-base tumors.
Magnetic resonance elastography can non-invasively quantify the mechanical properties of brain tumors.
