TABLE 1: 
Baseline values of PET variables and CBF response to acetazolamide in the cerebellar hemispheres contralateral and ipsilateral to the supratentorial infarction
VariableHemisphere
ContralateralIpsilateral
CBF (mL/100g/min)43.0 ±7.555.0 ±8.8
CMRO2 (mL/100g/min)3.29 ±0.48*4.01 ±0.34
OEF (%)45.4 ±5.5*43.3 ±5.0

CBF change (%)60.6 ±23.654.4 ±22.6
  • Note.—Values are the mean ± SD. CBF signifies cerebral blood flow; CMRO2, cerebral metabolic rate of oxygen; OEF, oxygen extraction fraction; CBV, cerebral blood volume; CBF change, the change of CBF during acetazolamide administration.
  • * P < .005 versus corresponding value in the contralateral cortex (Wilcoxon signed-rank test).
  • † P < .05.
