Abstract
The measurement of absolute concentration of 31P metabolites is described, using water 1H as an internal concentration standard. An analysis of the effect of variations in coil Q on flip angle and sensitivity is presented and verified experimentally. Concentrations of nucleoside triphosphate in rat brain and muscle have been measured.
摘要
描述了使用水1H作为内浓度标准来测量31P代谢物的绝对浓度。给出了线圈品质因数变化对翻转角和灵敏度影响的分析，并通过实验进行了验证。已测量了大鼠脑和肌肉中核苷三磷酸的浓度。
