Positron emission tomography values in the hemisphere ipsilateral and contralateral to the diseased artery.
| Hemisphere |
||
|---|---|---|
| Variable | Ipsilateral | Contralateral |
| CBF (ml/100 g/min) | 30.7 ± 5.2** | 33.9 ± 4.6 |
| CMRO2 (ml/100 g/min) | 2.91 ± 0.67* | 3.06 ± 0.63 |
| OEF (%) | 54.2 ± 10.1** | 51.7 ± 9.8 |
| CBV (ml/100 g) | 4.23 ± 0.70 | 3.98 ± 0.62 |
| 18F-FPYBF-2 (DVR) | 0.88 ± 0.10 | 0.89 ± 0.11 |
Values are reported as mean ± standard deviation.
CMRO2, cerebral metabolic rate of oxygen; OEF, oxygen extraction fraction; DVR, distribution volume ratio.
*P < 0.05, and **P < 0.01 vs. corresponding value in the contralateral hemisphere (Wilcoxon signed-rank-tests).
Normal values for CBF, CMRO2, OEF, and CBV in the 7 controls were 44.6 ± 4.5, 3.43 ± 0.33, 44.5 ± 3.8, and 3.98 ± 0.48, respectively.
