摘要：

We have developed a method for the absolute quantification of triple-quantum-filtered spectra of spin-3/2 nuclei. The method is illustrated by measuring the amount of intracellular Na+ in the perfused rat heart. There is good agreement between the result determined by the triple-quantum method and that measured using a simple single-quantum pulse-and-collect experiment. © 1991.
