| Abstract: | Recent advances in magnetic resonance imaging (MRI) technology have moved imaging beyond anatomical assessment to characterization of tissue composition. There are now clinically validated MRI-based quantitative techniques for assessing liver fat, iron, and fibrosis, and MRI is now routinely used in metabolic liver disease evaluation in both pediatric and adult patients. These MRI techniques provide noninvasive quantitation of liver metabolic biomarkers that are increasingly relied upon in the clinical management of pediatric patients with nonalcoholic fatty liver disease, metabolic syndrome, and hemochromatosis and/or hemosiderosis. This article provides a review of the clinical indications and technical parameters for performing metabolic liver MRI in the pediatric population, along with common pearls and pitfalls encountered during its performance. |
