A significant negative correlation could be seen between lactate and CBF-MD (r = −0.468, p = 0.009). Lactate also negatively correlated with global CBF (r = −0.408, p = 0.025) but this did not remain significant following Bonferroni correction. There was a weak negative and non-significant correlation between L/P ratio and CBF-MD (r = −0.364, p = 0.048) and global CBF (r = −0.329, p = 0.075). No significant correlation could be found between CBF and glucose, pyruvate, glycerol, and glutamate.
