Computed tomographic angiography versus conventional angiography for the diagnosis of blunt cerebrovascular injury in trauma patients.

Background: Blunt cerebrovascular injuries (BCVI) in trauma patients are rare but potentially devastating injuries, particularly if the diagnosis is delayed. Conventional angiography (CA) has been the screening and diagnostic modality of choice for identifying BCVI. With the advent of high-resolution computed tomography (CT), CT angiography has become a common modality for the screening of BCVI.
