Brain CT perfusion provides additional useful information in severe traumatic brain injury

Abstract

Background: The role of brain CT perfusion (CTP) imaging in severe traumatic brain injury (STBI) is unclear. We hypothesised that in STBI early CTP may provide additional information beyond the non contrast CT (NCCT). Methods: Subset analysis of an ongoing prospective observational study on trauma patients with STBI who did not require craniectomy and deteriorated or failed to improve neurologically during the first 48 h from trauma. Subsequently to follow-up NCCT, a CTP was obtained. Additional findings were defined as an area of altered perfusion on CTP larger than the abnormal area detected by the simultaneous NCCT. Patients who had additional finding (A-CTP) were compared with patients w..
