Multifrequency MR elastography
(MMRE) was applied to 32 obese pediatric patients with non-alcoholic fatty liver disease (NAFLD). Magnitude shear modulus
|G*| which relates to liver
stiffness is sensitive to differentiate mild fibrosis (F0-2) from severe fibrosis
(F3) with an AUROC of 0.93. The liver stiffness was positively correlated with serum
alanine aminotransferase (ALT) and can
potentially serve as a quantitative imaging marker for the noninvasive
assessment of liver fibrosis in patients with NAFLD.
