Abstract
Until the results of early intervention trials are known, computed tomography should be used selectively rather than routinely in all patients with stroke. Scanning may be advised in young patients (under 65 years) or in those with an atypical course where there is diagnostic doubt and computed tomography would influence management. The cost and medicolegal implications of routine scanning are enormous and should be considered carefully in relation to other and possibly more effective strategies.
摘要
在早期干预试验结果明确之前，计算机断层扫描（CT）在所有中风患者中应选择性使用，而非常规使用。对于年轻患者（65岁以下）或病程不典型、存在诊断疑问且CT结果会影响治疗方案的患者，可建议进行扫描。常规扫描的成本和法医学影响巨大，与其他可能更有效的策略相比，应谨慎考虑。
