Functional and Anatomical Magnetic Resonance Imaging (MRI) of Chronic Brain Injury and Hyperbaric Oxygen (HBO2) Study Subjects (HYBOBI-MRI)
MRI & CT Angiogram and Hyperbaric Oxygen in Chronic Stable Brain Injury
연구 개요
상태
상세 설명
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.

Hyperbaric oxygen
In this open-label feasibility study, all subjects will receive 60 hyperbaric oxygen sessions (100% oxygen, 1.5 atmospheres absolute (atm abs), for 60 minutes), delivered daily, five days per week.
|
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.

Auditory functional magnetic resonance imaging (fMRI) activation
기간: Within 2 weeks of final hyperbaric session
|
The first prime outcome measure will be auditory functional magnetic resonance imaging (fMRI) activation, comparing post-hyperbaric oxygen to pre-hyperbaric oxygen.
This is a categorical variable: absent, mild, moderate, normal, and increasing.
We will look at the difference between pre-hyperbaric (pre-HBO2) and post-hyperbaric (post-HBO2) scans graphically and descriptively, with the percentage of patients who show any improvement (any change towards normal).

Computed tomography angiography (CTA) Brain Perfusion
기간: Within 2 weeks of the final hyperbaric session
|
Pre-hyperbaric (pre-HBO2) computed tomography angiography (CTA) results will be determined to be normal or abnormal, and then compared to the post-hyperbaric (post-HBO2) scan, which will be scored as better, worse, or no change.
