Abstract

An efficient scheme for quantitatively mapping the three-dimensional distribution of the sodium ion in vivo using magnetic resonance imaging is described. To make the methodology totally quantitative, the data acquisition scheme is performed with very short echo times and negligible T1 saturation. Removal of signal variation due to imperfect radiofrequency (RF) response is accomplished using RF inhomogeneity maps acquired during each study. The high efficiency of the k-space trajectories allows the entire data collection process to be performed in under 10 min. The theory underlying the data collection and processing scheme is described along with representative examples acquired at 1.5 and 3.0 T.
