Imaging Traumatic Brain Injury On and Off the Battlefield
Deployed military personnel routinely work in hostile environments with significant exposure to potentially injurious blasts. Traumatic Brain Injury (TBI) secondary to blast has been labeled a signature injury mechanism. Blast injuries are a medical challenge for physicians in recent conflicts, with multiple blast injuries everyday among US military personnel . In the previous chapter, I showed an imaging spectrum of severity in penetrating head injuries as a guide for providers to tailor imaging with clinical suspicion. The majority of Traumatic Brain Injury seen clinically in combat is mild TBI (mTBI). The remaining severity injuries are moderate, severe, and penetrating (that can be further classified mild, moderate, severe) TBI. Mild TBI is injury with loss of consciousness, or altered mental status such as dazed or confused , or sometimes referred to as concussion .
