Table 2. Clusters of Significant (P < 0.05) Relative Regional Cerebral Blood Flow (rCBF) Decreases in the Sevoflurane Group

Clusters of voxels showing statistically significant relative rCBF reductions between adjacent levels. Coordinates (in mm) are given for the most significant voxel (bold ) and other depicting local maxima. Origo is at the intersection of midline, anterior commissure, and AC-PC line. Only clusters with P < 0.05 and extent >30 are considered significant.

CBL = cerebellum; R = right hemisphere; L = left hemisphere; MAC = minimal alveolar concentration.
