Outline of Final Research Achievements

Regarding the measurement of brain temperature, various methods using magnetic resonance (MR) imaging have been proposed in the past. Among these MR methods, the most clinically applicable approach may be the diffusion-weighted images (DWI) -thermometry method, which utilizes post-processed data from DWI. This DWI-based method, however, is relatively recent and insufficient yet in its analysis. Therefore, further detail study and evaluation will be needed.
Lateral ventricular (LV) temperature measurement was carried out successfully using DWI-thermometry. Slice thickness was found to have significant effects on the calculation of LV temperature, and furthermore, thinner slice thickness was considered to produce better results than thicker slices. Also we confirmed that LV temperature would change along with tympanic temperature.
