In this study, we used an optimized GRE sequence to measure tissue sodium T1 and T2 in human calf muscle in vivo at 3T. The measured sodium T1 in calf is 15.1ms, whereas the sodium short T2 component is 1.8ms, and long T2 component 28.7ms, which are in accord with literature reported values. These data permit the absolute determination of muscle sodium levels on a voxel by voxel basis in vivo.
