Advanced neuroimaging applied to veterans and service personnel with traumatic brain injury: state of the art and potential benefits.

Traumatic brain injury (TBI) remains one of the most prevalent forms of morbidity among Veterans and Service Members, particularly for those engaged in the conflicts in Iraq and Afghanistan. Neuroimaging has been considered a potentially useful diagnostic and prognostic tool across the spectrum of TBI generally, but may have particular importance in military populations where the diagnosis of mild TBI is particularly challenging, given the frequent lack of documentation on the nature of the injuries and mixed etiologies, and highly comorbid with other disorders such as post-traumatic stress disorder, depression, and substance misuse. Imaging has also been employed in attempts to understand better the potential late effects of trauma and to evaluate the effects of promising therapeutic interventions.

Radiomanometry is a modified technique for visualisation of the auditory tube. The contrast material is injected through a perforated tympanic membrane with control of injection pressure. Three positions are recommended: sub-mento-vertical, Worms, and modified Stenvers.
