Abstract
Sodium MR images are usually low in resolution due to an inherently low signal-to-noise ratio. We have optimised a Cartesian gradient echo sequence for a nominal 2mm isotropic resolution. Images of a male volunteer acquired in 16 sessions were co-registered and averaged. The resulting sodium images show detailed anatomy and excellent correspondence to proton anatomical reference images.
