3428中风2012年12月，更严格的斑点体征定义（表2-4）。另一个对观察到斑点征的频率有实质性影响的因素是症状发作和CTA之间经过的时间。随着从症状发作到初始CTA的时间增加，斑点征出现的频率降低。12，18-20由于只有少数研究检查了在症状发作6小时后进行初始CTA的ICH患者中斑点征的频率，因此有必要进一步研究该延长时间窗内斑点征的准确性。
3428 Stroke December 2012 for the stricter spot sign definition (Tables 2–4). Another factor with substantial effect on the frequency with which the spot sign is observed is the time elapsed between symptom onset and CTA. As the time from symptom onset to initial CTA increases, the frequency of spot sign appearance decreases. 12, 18–20 Because only a few studies have examined the frequency of the spot sign in ICH patients whose initial CTA is performed beyond 6 hours of symptom onset, further research is warranted on the accuracy of the spot sign in this extended time window.
