Synopsis

Keywords: New Devices, ElastographyA specialized driver was developed to enable magnetic resonance elastography of the parotid and other salivary glands using high shear wave frequencies to provide improved spatial resolution and optimized ergonomics. The performance of this new device was tested in volunteer studies. Preliminary results showed that suitable shear wave illumination of the parotid gland is possible at frequencies as high as 120 Hz and that high-frequency shear wave MR elastography of the parotid gland is feasible.
