Cerebral blood flow and metabolism in the symptomatic and asymptomatic patients
| Asymptomatic Patients | Symptomatic Patients | P | |
|---|---|---|---|
| CBF (mL · 100 g−1 · min−1) | 44.7 ± 6.0 | 40.5 ± 8.7 | .36 |
| OEF (%) | 42.9 ± 5.7 | 48.5 ± 5.7 | .11 |
| CBV (mL · 100 g−1) | 3.3 ± 0.4 | 3.3 ± 0.7 | .92 |
| CMRO2 (mL · 100 g−1 · min−1) | 4.9 ± 1.4 | 4.9 ± 1.8 | .97 |
| CBF/CBV (min−1) | 9.7 ± 2.8 | 9.1 ± 3.4 | .77 |
Note:—CBF indicates cerebral bloodflow; OEF, oxygen extraction fraction; CBV, cerebral blood volume; CMRO2, cerebral metabolic rate of oxygen.
