| CBF (mL/min/100 g) | 5 | 25.0 ± 2.8 | 33.0 ± 4.2 | 0.76 ± 0.05 | P < 0.0001 |
| CVR (%) | 5 | 25.0 ± 4.0 | 29.0 ± 8.6 | 0.95 ± 0.35 | NS |

| CBF (mL/min/100 g) | 5 | 34.3 ± 2.6 | 41.4 ± 1.8 | 0.83 ± 0.08 | P < 0.0001 |
| CMRo2 (mL/min/100 g) | 5 | 2.3 ± 0.3 | 2.9 ± 0.3 | 0.80 ± 0.03 | P < 0.0001 |

I/C ratio = ipsilateral/contralateral ratio; NS = not significant; FMZ-BP = BP for 11C-FMZ.
Five patients included in study were patients 2, 10, 11, 12, and 13 (Table 1).
