  • Note:—IPAT indicates integrated parallel acquisition technique; SNR, signal-to-noise ratio; CNR, contrast-to-noise ratio; A1 and A2, A1 and A2 segments of anterior cerebral artery; M1, M2, and M3, M1, M2, and M3 segments of middle cerebral artery; P2 and P3, P2 and P3 segments of posterior cerebral artery; BA, basilar artery. Statistically significant results are marked with asterisks.
