11. 4/7/2015November 200911© 2011 Boston Medical Center Head Trauma “High-energy forces associated with impact or violent shaking result in a variety of CNS injuries that can be detected my modern neuro-imaiging techniques. The evolution of these injuries, as well as.. Secondary [injuries], are often effectively displayed on serial imaging studies” AAP Section on Radiology, 2009
