Brain temperature is known to increase in severe head trauma patients. In mild head trauma cases, however, temperature measurement is not possible and the alteration in brain temperature has not been assessed. We tried assessing their cerebral ventricular temperature by DWI. 20 patients of within-30-day from mild head trauma were compared with the normal controls (14 subjects). 4 patients at the over-30-day period were compared to other groups. In our study, the temperature difference was found statistically significant when within-30-day and normal controls were compared. This decrease in temperature was considered to be the reflection of decline in metabolism.
