Traumatic brain injury (TBI) is a leading cause of post-injury hospitalization, disability, and death worldwide. In Nova Scotia, approximately 50% of major trauma reported is head trauma. TBI is predicted to be the most common and expensive neurological condition in Canada through the year 2031. Families and medical teams must often decide on the appropriate level of care for patients with severe TBI and frequently need to consider withdrawal of life support measures. These decisions have implications for patients with severe TBI, costs to the health care system, and rates of organ donation. A reliable method for neurological evaluation at the time of the patient's arrival to the hospital is important, because it is possible that many patients with severe TBI already have permanent brain damage. Assessing this brain damage with clinical tests is difficult because of the nature of patients' injuries and the sedative medication they receive at the time of their hospital admission. Current standard imaging technique for these patients is severely limited in the assessment of the extent and severity of the brain damage. Advanced diagnostic imaging, called Computed Tomography Perfusion (CTP), can help detect permanent brain damage. However, CTP of the head is not currently done for patients with severe TBI when they arrive at the hospital. The investigators want to test whether CTP of the head can detect permanent brain damage among patients with severe TBI.
