Abstract :
The objective of this study is to evaluate the correlations between the quantitative MRI parameter, T2 relaxation time, and the viscoelastic storage modulus for low concentrations of agarose gel. T2 values were determined from MR image maps generated by a 3T scanner. The storage modulus was measured by dynamic mechanical analysis (DMA). It was found that the T2 values decreased, while the storage modulus increased, with higher agarose concentrations.
