The United States Military is developing new techniques to assess closed head traumas. These methods include a new scanning camera that uses gamma rays and radioisotopes. Col. John Cho, commander of the Evans Army Community Hospital at Fort Carson, made this announcement Tuesday April 24, 2007. This research has been in response to a recent study at Fort Carson that found that 18 percent of troops (2,392 of 13,400) who had been to Iraq suffered at least some brain damage from the blasts of improvised explosive devices.
