Within session and between session variability of metabolites for whole brain proton spectroscopy.

Individual region of interest measurements for within session reproducibility obtained in the first and second imaging sessions in 17 and 16 subjects respectively, and the between session reproducibility for those 22 subjects who underwent imaging at both sessions. Data displayed are standard deviation for metabolite ratios (Choline (Cho)/Creatine (Cr), N-Acetyl aspartate (NAA)/Choline and NAA/Cr.

针对分别完成首次成像扫描会话的17名受试者与完成第二次成像扫描会话的16名受试者，获取了用于评估会话内可重复性的单个感兴趣区（region of interest, ROI）测量数据；同时还包含了22名两次扫描均完成的受试者的会话间可重复性数据。本次展示的数据为代谢物比值的标准差，具体包括胆碱（Cho）/肌酸（Cr）、N-乙酰天冬氨酸（NAA）/胆碱以及NAA/Cr三组比值。
