We evaluated the pharmacologically induced hypothermia treatment response in focal cerebral ischemia induced white matter injury in a mice model using DTI. Results indicated that significantly reduced infraction volume in the treatment group compared to control group. Significantly decreased FA and λ// were only found in the ipsilateral external capsule and fornix than contralateral sides in control group. Less reduction of FA and λ// were found in the hypothermia treated group. Our results support the use of DTI as a biomarker to non-invasively monitor the hypothermia treatment response in ischemia induced stroke injury.
