Detection of Liver Fibrosis Using Magnetic Resonance Elastography

Abstract

Abstract:

Magnetic resonance elastography can be used to measure the elastic stress of the liver and the extent of hepatic fibrosis quantitatively. This paper describes the principles and practical implementation of magnetic resonance elastography, including tissue biomechanical model analysis, development of the shear wave developing stimulator, design of elastic imaging sequence and fitting algorithms for elastography. Magnetic resonance elastography measurements on ex vivo pork liver and human volunteers were demonstrated experimentally.

Key words: magnetic resonance elastography, hepatic fibrosis, local frequency estimation, elasticity, liver
