In this study, we aimed to develop a new method to detect the abnormality in cerebral metabolism using brain temperature calculated from diffusion tensor parameters and validate the possibility in the measurement. Our results agree withthe follo wing two hypotheses: 1) the brain temperature in patient who showed cognitive impairment after CEA may be lower than that before CEA, 2) the brain temperature in patient who showed improvement of cognition after CEA may be higher than that before CEA. Our research presented the availability of the brain temperature measured by diffusion tensor imaging in higher strength of magnetic fields for detecting the abnormality of cerebral metabolism.
