Neurocognitive and behavioral symptoms can persist for some TBI patients, despite the absence of imaging findings on routine imaging. A forensic population of 172 patients that underwent trauma imaging protocol, were divided by injury severity and imaging findings. Majority of subjects were classified as being mild, 77.3%. For each severity group the rates of positive findings in acute CT, FLAIR and SWI sequences are described. The importance of using newer imaging techniques for TBI subjects that shows persistent symptoms is highlighted.
