Functional and Anatomical Magnetic Resonance Imaging (MRI) of Chronic Brain Injury and Hyperbaric Oxygen (HBO2) Study Subjects
The purpose of this study is to evaluate Brain MRI (Magnetic Resonance Imaging), and Brain CT (Computed Tomography) Angiogram data in subjects who participate in the "Hyperbaric Oxygen for Chronic Stable Brain Injury" (HYBOBI) study. Including information from MRI and CT studies provide information about whether hyperbaric oxygen improves brain function in subjects who have had a brain injury. Subjects will complete MR and CT scans twice during the study. The first MR and CT will be performed prior to the first hyperbaric session of the HYBOBI study, and the second will be performed within two weeks following the last hyperbaric session.
In an ongoing feasibility study (HYBOBI), brain-injured subjects are exposed to hyperbaric oxygen at 1.5 atmospheres for 60 minutes. They receive this exposure five days per week, and receive 60 total sessions. Prior to hyperbaric oxygen, these study subjects have neurologic, cognitive, and functional measures. The measures are repeated at the conclusion of 60 hyperbaric oxygen sessions, and again six months later. The goal of the HYBOBI feasibility study is to learn about these patients and determine possible hyperbaric oxygen effects, if any, to prepare for a blinded randomized controlled clinical trial.
This study adds an imaging component to the HYBOBI study, further investigating brain changes in participants. Participants will undergo Brain MRI (Magnetic Resonance Imaging) using a 3 tesla magnet, and Brain CT (Computed Tomography) Angiogram. Subjects will undergo imaging before receiving hyperbaric oxygen and within 2 weeks of completion of the 60 hyperbaric sessions.

Medical and Biotech [MESH] Definitions
Descriptive anatomy based on three-dimensional imaging (IMAGING, THREE-DIMENSIONAL) of the body, organs, and structures using a series of computer multiplane sections, displayed by transverse, coronal, and sagittal analyses. It is essential to accurate interpretation by the radiologist of such techniques as ultrasonic diagnosis, MAGNETIC RESONANCE IMAGING, and computed tomography (TOMOGRAPHY, X-RAY COMPUTED). (From Lane & Sharfaei, Modern Sectional Anatomy, 1992, Preface)
Magnetic Resonance Spectroscopy
Spectroscopic method of measuring the magnetic moment of elementary particles such as atomic nuclei, protons or electrons. It is employed in clinical applications such as NMR Tomography (MAGNETIC RESONANCE IMAGING).
Whole Body Imaging
The creation of a visual display of the inside of the entire body of a human or animal for the purposes of diagnostic evaluation. This is most commonly achieved by using MAGNETIC RESONANCE IMAGING; or POSITRON EMISSION TOMOGRAPHY.
The use of molecularly targeted imaging probes to localize and/or monitor biochemical and cellular processes via various imaging modalities that include RADIONUCLIDE IMAGING; ULTRASONOGRAPHY; MAGNETIC RESONANCE IMAGING; fluorescence imaging; and MICROSCOPY.
Cardiac Imaging Techniques
Visualization of the heart structure and cardiac blood flow for diagnostic evaluation or to guide cardiac procedures via techniques including ENDOSCOPY (cardiac endoscopy, sometimes refered to as cardioscopy), RADIONUCLIDE IMAGING; MAGNETIC RESONANCE IMAGING; TOMOGRAPHY; or ULTRASONOGRAPHY.
