Core Tip
Core tip: Magnetic resonance spectroscopy (MRS) is thought to be the noninvasive gold standard in the quantification of hepatic steatosis. The present study investigated the accuracy of magnetic resonance imaging (MRI) in quantifying liver fat content in Chinese children and adolescents, with MRS as a reference. MRI and MRS were performed with multi-echo Dixon and HISTO sequences, respectively, to calculate hepatic proton density fat fraction. Multi-echo Dixon showed an excellent correlation and agreement with MRS in quantifying liver fat content, indicating that it could be a potential tool to detect hepatic steatosis in Chinese children and adolescents.
