MR elastography is a technique that allows the assessment of mechanical properties of tissues that may be affected by disease processes. We designed and tested a new driver to allow MRE to be performed in the head and neck using a commercially available transducer, headrest moulds and piston extensions. This new driver design was simple to implement and comfortable to use. Our initial results showed that the performance of the driver was satisfactory and provided reproducible results for the normal parotid glands. This simple driver may allow a more widespread application of this technique to study head and neck pathologies.
