Natural abundance 13C NMR spectra obtained from 144-cm3 volumes in the human brain contained well-resolved resonances of myo-inositol after 60 min of data accumulation. A mean concentration of 7.2 +/- 0.5 mumol/g (+/- SE, n = 7) was calculated from the comparison with phantoms. 13C NMR spectroscopy thus provides a complementary role in the quantitation of metabolites also observed in the crowded 1H spectrum.
从人脑144立方厘米体积中获取的天然丰度13C核磁共振谱,在积累60分钟数据后,包含了分辨率良好的肌醇共振峰。通过与体模比较,计算出平均浓度为7.2±0.5微摩尔/克(±标准误,n = 7)。因此,13C核磁共振波谱学在定量分析拥挤的1H谱中也能观察到的代谢物方面发挥着补充作用。
