Abstract
The use of thulium 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetrakis(methylene phosphonate (TmDOTP5-) as an in vivo 23Na NMR shift reagent for rat liver was evaluated by collecting interleaved 23Na and 31P spectra. Infusion of 80 mM TmDOTP5- without added Ca2+ produced baseline-resolved peaks from intra- and extracellular sodium without producing any changes in phosphate metabolite resonances or intracellular pH. Several key physiological parameters measured in parallel groups of animals confirmed that liver physiology is largely unaffected by this shift reagent
