title: 23Na NMR maps of head sized phantoms and a low resolution 23Na map of the live human head.
abstract: An NMR system capable of obtaining 23Na NMR signals and scans from large objects containing biological concentrations of sodium in a 411 gauss magnetic field in less than one hour was developed. Scans were carried out on 6"-8" diameter phantoms containing 150 mM NaCl and the first low resolution 23Na NMR map of a live human head was obtained.
