- Elastic Measurement using MRI
抄録
This paper describes the method to estimate the shear modulus and the viscosity of an elastic material with MRE (magnetic resonance elastography), which is one of MRI (magnetic resonance imaging) sequences and enables to measure elastic information of a biomedical organ in vivo with giving vibration to a measurement object. The shear modulus could be calculated from the phase change of the observed MRE signal and the viscosity from the amplitude attenuation. Here, we estimated elastic values of phantoms with PVA (polyvinyl alcohol) and agarose gel. Simultaneously, the elastic values were measured invasively using the dynamic test that is the typical measurement method for elastic information. The elastic values obtained from both methods show the good correlation, which indicates that MRE has the useful methodology to obtain the elastic information non-invasively.
