In this communication, we show an example of free yttrium Y3+ being complexed with 1,4,7,10-tetrakis(acetamido)-1,4,7,10-tetraazacyclododecane (DOTAM) to form [Y(DOTAM)(H2O)](3+) as a model for gadolinium in contrast agents.Magnetic ResonanceIn-VivoNmrIsomersWatertext::journal::journal article::research article
