| Research Abstract |
Tagging magnetic resonance imaging(MRI) provides a noninvasive means of displaying the internal motion of tissues with high accuracy. The purpose of this study was to develop a method for generating the maps of elastic modulus in internal soft tissues using tagging MRI. To evaluate the accuracy of our method, we actually measured the relationship between the pressure and strain using a material testing machine and compared with the results obtained by our method. We also applied this method to the hepatic and femoral images of human volunteers. These results suggest that our method is useful for tissue elasticity imaging.
