Abstract: ObjectiveTo explore the characteristics of the metabolite concentrations of the precentral gyrus in healthy Chinese adults using proton magnetic resonance spectroscopy (1H-MRS).Methods 1H-MRS was carried out in 92 healthy Chinese adult volunteers. The metabolite ratios of NAA/Cr, Cho/Cr and NAA/Cho were compared and analysed.ResultsNo significant changes of NAA/Cr, Cho/Cr and NAA/Cho ratios were observed between the left and right precentral gyrus, nor between the male and female. However, the precentral gyrus NAA/Cr and NAA/Cho ratios were decreased gradually with aging and Cho/Cr ratios were increased gradually with aging.ConclusionThe characteristics of the precentral gyrus metabolite concentrations in healthy Chinese adults have been obtained.

Key words: healthy adults, Chinese, precentral gyrus, proton magnetic resonance spectroscopy
