Mean brain temperature for 47 brain regions delineated by the Automated Anatomical Labeling (AAL) atlas, with estimates of the upper and lower bounds of Minimal Detectable Change (MDC) at which temperatures may be above- or below-typical, respectively. Brain temperature was non-invasively derived from volumetric magnetic resonance spectroscopic imaging (MRSI) data. Voxel-level brain temperature was calculated according to the following equation: TCRE = −102.61(ΔH20−CRE) + 206.1°C, where ΔH20−CRE = chemical shift difference between the creatine and water resonances. The upper bounds of MDC are indicated in dark gray bands, and the lower bounds of MDC are indicated in light gray bands.
