Task: Answer Verification
Input (English): Question: Is early repeat imaging warranted for high-grade blunt cerebrovascular injuries?
Answer: Injury grade of BCVIs is associated with the healing rate of the injury. While approximately half of Grade I BCVIs resolved, only 7% of all high-grade injuries healed. Early repeat imaging may not be warranted in high-grade BCVI; the vast majority of injuries do not resolve. The cost, radiation, and transport risk of early repeat imaging should be weighed against the potential treatment impact for individual patients.
Output (English): no
