FIG 3. Comparison of the relationship between brain temperature measured from sensors implanted into the infarcted and contralateral non-infarcted tissue versus the chemical-shift differences between H₂O and NAA (left) and between H₂O and TMA (right). Only data collected using a TE of 136 ms are depicted. The lines show the best fit by linear regression analysis. There was no significant difference in the slope or elevation of the data collected from the infarct compared with the non-infarcted tissue.
