MR spectroscopy of liver in overweight children and adolescents: Investigation of 1H T2 relaxation times at 3Â T

1H MRS at 3 T is an effective technique for measuring hepatic fat content in overweight and obese children and adolescents. It is necessary to measure T2 relaxation values and to correct the spectra for the T2 relaxation effects in order to obtain an accurate estimate of the hepatic fat content.
