Traumatic brain injury disrupts the complex anatomy of the afferent and efferent visual pathways. Injury to the afferent pathway can result in vision loss, visual field deficits, and photophobia. Injury to the efferent pathway primarily causes eye movement abnormalities resulting in ocular misalignment and double vision. Injury to both the afferent and efferent systems can result in significant visual disability.

The mechanisms for regulating cerebral blood flow (CBF) are highly sensitive to traumatic brain injury (TBI). The perfusion imaging technique may be used to assess CBF and identify perfusion abnormalities following a TBI. Studies have identified CBF disturbances across the injury severity spectrum and correlations with both acute and long-term indices of clinical outcome. Although not yet widely used in the clinical context, this is an important area of ongoing research.

ReviewConventional MR Imaging in Trauma Management in Pediatrics.
Traumatic brain injury (TBI) is a major cause of death and disability in children across the world. The aim of initial brain trauma management of pediatric patients is to diagnose the extent of TBI and to determine if immediate neurosurgical intervention is required. A noncontrast computed tomography is the recommended diagnostic imaging choice for all patients with acute moderate to severe TBI. This article outlines the current use of conventional MR imaging in the management of pediatric head trauma and discusses potential future recommendations.
