A case study of magnetic resonance imaging of cerebrovascular reactivity: A powerful imaging marker for mild traumatic brain injury

Primary objective: To use breath-hold functional magnetic resonance imaging (fMRI) to localize the brain regions with impaired cerebrovascular reactivity (CVR) in a female patient diagnosed with mild traumatic brain injury (mTBI). The extent of impaired CVR was evaluated 2 months after concussion. Follow-up scan was performed 1 year post-mTBI using the same breath-hold fMRI technique.Research design: Case report.Methods and procedures: fMRI...
