|---|---|---|---|---|
| Pre-revascularisation | Post-revascularisation | Pre-revascularisation | Post-revascularisation | |
| Intact CoW | 0.131±0.044 | 0.197±0.041 | 0.024±0.016 | 0.147±0.005 |

All values in per cent MR signal change/mm Hg, mean±SE.
No significant differences were seen between those with and without an intact CoW.
ACoA, anterior communicating artery; CoW, circle of Willis; CVR, cerebrovascular reactivity; MCA, middle cerebral artery; PCoA, posterior communicating artery.
