Abstract： 目的 评价双源CT Flash大螺距模式在头颈心动脉血管联合成像中的临床应用价值.方法 回顾性分析在日照市人民医院就诊的应用双源CT Flash大螺距模式头颈心动脉血管联合成像扫描的100例患者的临床资料,其中阳性结果的患者中有27例接受头颈部血管造影(DSA)检查,38例接受冠状动脉DSA检查,评价双源CT Flash大螺距模式头颈心动脉血管联合成像的图像质量,结果与DSA进行对照统计.结果 冠状动脉血管显示总体满意率为93%,颈动脉颅外段(CA-E)血管显示总体满意率为99%,颈动脉颅内段(CA-I)血管显示总体满意率为95%,脑血管(大脑前动脉+大脑中+大脑后动脉)血管显示总体满意率为97%.阳性患者后处理图像诊断结果与DSA对照,狭窄吻合率基本一致,尤其重度及闭塞吻合率均达到95%以上.结论 双源CT Flash大螺距模式头颈心动脉一站式联合成像是一种快速方便、准确无创的新检查手段,能准确全面地评估头颈心动脉血管粥样硬化狭窄程度,对早期干预、降低心脑血管事件的发生具有临床意义.
