Targeted temperature management is a treatment that seeks to reduce and control the body temperature. We demonstrate a novel localized cooling technique using high flow cold air applied nasally and orally to the airways by monitoring the brain temperature using gradient echo phase imaging at 3T. 2 healthy volunteers were investigated, with one subject being scanned twice and the other once. A significant temperature reduction (p<0.05) was seen in the inferior frontal lobe in all three experiments with an average cooling effect of -0.33°C. This demonstrates the feasibility of our proposed high flow cold air system.
