The evaluation of lanthanide-based MRI contrast agents often requires the quantification of concentrations of the agents in ex vivo tissues to validate in vivo results. We have developed a BMS NMR spectroscopy method that can quantify the concentrations of lanthanide-based agents in ex vivo tissues, which has an outstanding yield of 93, excellent precision within ~1 mM, and acceptable sensitivity approaching 0.1 mM.
