Children were asked to fast for 4 hours before the MRI exam and were scanned at 3T (Signa EXCITE HDxt scanner, GE Medical Systems, Waukesha WI) in a supine position with an eight-channel torso phased-array coil centered over the liver. A dielectric pad was placed between the coil and the abdomen. Each MR exam included chemical-shift-encoded MRI-M and MRI-C techniques as illustrated in Figure 1 and described below. Acquisition parameters are summarized in Table 2. Both techniques assumed exponential R2* signal decay and applied the same multi-peak fat spectral model derived from human liver triglyceride composition (28 (link)).
