Baseline values of PET variables and CBF response to acetazolamide in the cerebellar hemispheres contralateral and ipsilateral to the supratentorial infarction
| Variable | Hemisphere | |
|---|---|---|
| Contralateral | Ipsilateral | |
| CBF (mL/100g/min) | 43.0 ±7.5 | 55.0 ±8.8 |
| CMRO2 (mL/100g/min) | 3.29 ±0.48* | 4.01 ±0.34 |
| OEF (%) | 45.4 ±5.5* | 43.3 ±5.0 |
| CBV (mL/100g) | 3.20 ±0.60* | 3.72 ±0.56 |
| CBF change (mL/100g/min) | 24.9 ±10.6† | 28.7 ±10.2 |
| CBF change (%) | 60.6 ±23.6 | 54.4 ±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.
