Development of a method to non-invasively measure the brain temperature using diffusion tensor imaging

在这项研究中，我们的目的是开发一种新的方法来检测脑代谢异常使用脑温度的扩散张量参数计算和验证的可能性，在测量。本研究结果符合以下两个假设：（1）CEA后出现认知功能障碍的患者脑温可能低于CEA前;（2）CEA后出现认知功能改善的患者脑温可能高于CEA前。本研究表明，在高强度磁场条件下，磁共振弥散张量成像测量脑温可用于检测脑代谢异常。

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.
