Comparison of T2*-oxygenation-ratio of volatile anesthetics among brain regions.

<p>Images are coronal T2* MRI sections acquired <i>in vivo</i> under general anesthesia using isoflurane (A: cortex, B: hippocampus, C: striatum, D: thalamus) or sevoflurane (F: cortex, G: hippocampus, H: striatum, I: thalamus). Box plots represent median, 25^th and 75^th percentile, minimum and maximum values, outliers (°) and extremes (*). Y-axis: regional T2*-oxygenation-ratio. X-axis: Cx, cortex; Hc, hippocampus; Str, stiatum; Th, thalamus. E: T2*-oxygenation-ratio for isoflurane. The thalamus had a lower oxygenation level than the other studied brain regions. J: T2*-oxygenation-ratio for sevoflurane. No significant difference was observed between the studied brain regions. *** p<0.001.
