Functional and Anatomical Magnetic Resonance Imaging (MRI) of Chronic Brain Injury and Hyperbaric Oxygen (HBO2) Study Subjects

Imaging of the brain without gadolinium will be performed with a 3 Tesla magnetic resonance (MR) System (Intera Achieva 3T; Philips Medical Systems). The protocol will include anatomical sequences, a diffusion tensor imaging sequence with fiber tracking, and auditory, visual, and motor functional magnetic resonance imaging (MRI).

Computed tomography angiography (CTA) with intravenous (IV) contrast will be performed on a 320 head computed tomography (CT) scanner, assessing brain perfusion.
