摘　　要：目的探讨基于FastStroke软件的多期CT血管成像(CTA)侧支循环评分在评估急性缺血性脑卒中患者侧支循环中的临床可靠性.方法回顾性分析51例前循环急性缺血性脑卒中患者,入组患者治疗前均进行了一站式CT检查及数字减影血管造影(DSA)检查.多期CTA均应用FastStroke软件进行后处理.结果FastStroke和DSA侧支循环评分方法的一致性检验Wighted Kappa系数分别为0.783[95%置信区间(CI)0.659~0.907]、0.854(95%CI0.753~0.956).基于FastStroke软件的多期CTA侧支循环评分与金标准DSA侧支循环评分具有很强的相关性(r=0.864,P<0.001).结论基于FastStroke软件的多期CTA侧支循环评分为一种可靠且快速的侧支循环评分方法,可为临床医生提供一种新的可视化侧支循环评分方法.Objective To explore the reliability of evaluation for collateral circulation in patients with acute ischemic stroke on FastStroke based multi-phase CT angiography(CTA)collateral circulation score.Methwds Fifty-one patients with anterior circulation acute ischemic stroke were retrospectively enrolled.All patients underwent one-stop CT examination and digital subtraction angiography(DSA).Multi-phase CTA images were post-processed by FastStroke software.Results The Weighted Kappa coefficient between two radiologists’evaluation for collateral circulation based on FastStroke and DSA were 0.783[95%confidence interval(CI)0.659—0.,907]and 0.854(95%C10.753—0.956),respectively.The FastStroke based multi-phase CTA collateral circulation score had a valid correlation with gold standard of DSA collateral circulation score(r=0.864,P<0.001).ConclusionThe FastStroke based multi-phase CTA collateral circulation score is a reliable and rapid method,which can provide a noval visual method for cliniacians on evaluation for collateral circulation.
