Combat-related TBI leads to significant mortality and morbidity. In our previous research, we have demonstrated that simulated aeromedical evacuation (AE), or hypobaria, worsens neurological outcomes after TBI and suggests that early AE of TBI patients contributes to secondary insults. To study the effects of such hypobaric exposure during early stage of injury we have constructed a MRI compatible hypobaric chamber that allows us to evaluate changes in metabolism, perfusion, and functional status in a preclinical model of brain injury. Here we demonstrate our initial experiences with the hypobaric chamber in the MRI to obtain in vivo imaging and spectroscopic data.
