High-Field Neuroimaging in Traumatic Brain Injury and Disorders of Consciousness

Traumatic brain injury (TBI) is a debilitating neurological disorder that occurs to the brain as a result of a trauma. Imaging is fundamental for the management, diagnosis and prognosis of TBI patients with or without disorder of consciousness in the different stages. This chapter provides the state of the art of the recent high-field neuroimaging techniques used in the clinical and scientific domains. Specifically, functional magnetic resonance imaging, diffusor tensor imaging, magnetic resonance spectroscopy and high- field and ultra-high field studies are described. Finally, recommendation to combining different imaging modalities for the TBI patients protocols are provided.
