Sodium MRI can provide unique metabolic information to study the human body and its afflictions. However, the low intrinsic signal to noise ratio of sodium MRI limits the resolution of the sodium images to 3-5 mm isotropic and necessitates long acquisition times (~10-20 min). The necessity to perform 1H and 23Na acquisitions sequentially also prolongs the total scan time and limits applications of combined proton-sodium imaging. In this work, we demonstrate a technique to simultaneously acquire sodium images and multi-parametric proton maps in one single scan.
