Abstract

SUMMARY
Magnetic resonance elastography of liver is a technique for evaluation of liver stiffness and is currently considered the most accurate non invasive imaging technology for evaluation of liver fibrosis. MRE used a phase-contrast sequence which examinate the propagation of mechnical waves in the liver parenchyma to generate to images depicting the stiffness of tissure. Hepatic fibrosis increases the stiffness. MRE can detected early fibrosis and evaluated stage of liver fibrosis through changes of the stiffness of liver parenchyma. MRE is more accurate than US elastography in the evaluation liver fibrosis. MRE has been used commonly in the word. Choray hospital is one of the first hospital to implement MRE in Viet Nam. In this lecture, we will introduce the basic principles, techniques and clinical applications of liver MRE.
