  • Values are mean±SD.

  • Comparative values for CBF, CMRO2 and OEF in the MCA, ACA and PCA distributions in normal volunteers were 52.5±6.0, 50.9±6.3, 60.3±7.1, 4.07±0.42, 3.80±0.40, 4.70±0.64, 44.8±3.4, 43.2±3.0 and 44.9±3.6, respectively.

  • * p<0.05, paired t test.

  • ACA, anterior cerebral artery; MCA, middle cerebral artery; PCA, posterior cerebral artery.
