ABSTRACT
The use of computed tomography (CT) and magnetic resonance imaging (MRI) in mild traumatic brain injury (mTBI) is overviewed in this chapter. Although in the majority of mTBI cases no abnormality will be shown, the common neuropathological changes that may be identified on CT and/or MRI are highlighted with an emphasis that such abnormalities provide only a macroscopic perspective of the pathology that may be viewed. Emphasis is placed on understanding the subtle nature of neuropathology that may accompany mTBI, the potential for dynamic changes that vary with time postinjury and that detection depends on which neuroimaging method is used. The role of advanced neuroimaging techniques that provide quantitative information about potential network-level damage using diffusion tensor imaging (DTI) and resting state functional MRI is overviewed with numerous examples provided that illustrate neuroimaging techniques that detect mTBI abnormalities.
