Tm(DOTP)5-, the thulium(III) complex of 1,4,7,10-tetraazacyclododecane-N,N',N'',N'''- tetra(methylenephosphonate), is introduced as a 23Na+ shift agent for use in discrimination of the NMR resonances of intra- and extracellular 23Na+ ions in perfused rat hearts. The novel shift agent is directly compared to the widely used Dy(TTHA)3- (dysprosium(III) triethylenetetraminehexaacetate).
