Imaging of sequelae of head trauma.

The imaging of head trauma has been one of the fundamental cornerstones of neuroradiology. As the practice of neuroimaging has matured, great strides have been made in the diagnostic as well as prognostic armamentarium available to physicians. Given the vast diversity of trauma mechanisms and clinical pathways, new advanced imaging technologies have had a lasting impact on the detection, description, and depiction of head trauma. Furthermore, these new tools are allowing the imaging specialist to function not only as an interpreter of what is seen but as a 21st century radiographic oracle. We present a comprehensive review of the imaging findings of sequlae of traumatic brain injury and the growing correlation of new neuroimaging techniques and neurotraumatic outcomes.
