Paper Abstract

Diffusion-weight imaging (DWI) has already been incorporated as a regular sequence for patients. If DWI could indicate brain temperature without a complicated procedure, such information may greatly contribute to initial diagnosis. The temperature (T: degree Celsius) was calculated using the following equation form the diffusion coefficient (D): T= 2256.74/ln (4.39221/D) - 273.15. The cerebrospinal fluid region for automated temperature computation was segmented by 2-dimensional region growing. No significant differences were seen between temperatures using the proposed method and the manually segmented. The proposed method of fully automated deep brain temperature computation from DWI may prove feasible for application in MRI consoles.
