This
work investigates the repeatability and reproducibility of total sodium
concentration (TSC) estimates in the human brain. Healthy volunteers were
scanned twice at two different sites using comparable 3D Cones acquisitions,
and region of interest TSC values were compared. Consistent TSC estimates were
observed across repeated scans at different sites, and, for robust multi-site
comparisons, a need was identified for standardisation of non-Cartesian data
reconstruction. These preliminary results provide an initial step in the technical
validation of sodium MRI-derived cancer biomarkers.
