Common questions
What does Blunt Cerebrovascular Injury Screening (Expanded Denver) do?
Use during trauma evaluation to identify patients who should undergo neck CTA based on BCVI signs/symptoms or high-risk injury mechanisms, since most BCVI is initially asymptomatic.
How is the result calculated?
Screen positive if any BCVI sign/symptom OR any high-risk factor is present → neck CTA recommended. Signs/symptoms drive a high-priority (emergent imaging) pathway; risk factors alone drive a screening pathway.
Is this a substitute for clinical judgement?
No. All results are decision-support only, for licensed clinicians. They must be individualized to the whole patient and the latest guideline version.
