In this study, we compare the spectroscopy-determined fat fraction given at 1.5T and 3T in human subjects examined at both field strengths on the same day. We find there is close agreement between the liver fat fraction measured by MR spectroscopic at 1.5T with that measured at 3T. For the measurements at the two field strengths to be in agreement, T2 correction is necessary.
