A tabletop magnetic resonance elastography (MRE) system
was developed based on a 0.5T permanent magnet for the
analysis of viscoelastic properties of tissue samples.
The system allowed us the measurement of viscoelastic
parameters in soft tissue samples in a frequency range
of 500-1000 Hz. The data are in good agreement to
published data acquired in a 7T-highfield
superconducting magnet. Acquiring the same
viscoelasticity information by low costs with little
requirements for space and maintenance might support MRE
developments towards mechanics based histopathology
capable to links viscoelastic constants with the
etiology and pathogenesis of diseases.
