Figure 6

No correlation between fractional anisotropy reductions and microdialysis measured brain metabolic markers. There was no correlation between fractional anisotropy (FA) z-scores and interstitial levels of glucose (A), lactate (B), lactate to pyruvate ratio (C), and glutamate (D) 13–36 h after initial injury (Spearman’s one-tailed correlation tests, n = 15). Z-scores are calculated as indicated in Fig. 3. Triangles indicate patients with conventional MRI abnormalities in the region of microdialysis catheter insertion and open squares correspond to the outlier as in Fig. 3.
