目的：探讨在头颈部CT动脉血管成像( CTA)中的生理盐水最佳注射流率。方法：选取2012年11月~2013年9月行双源CT头颈部CTA 84例患者为研究对象,按时间顺序等分为对照组、试验1组和试验2组,3组分别采用生理盐水注射流率为5.0 ml/s,5.5 ml/s,6.0 ml/s进行检查,比较3组患者的对比剂存留和不良反应发生情况。结果：试验2组对比剂存留明显少于对照组和试验1组(P<0.05)。3组患者不良反应比较差异无统计学意义(P>0.05)。结论：在头颈部CT检查中生理盐水注射流率为6.0 ml/s可明显消除对比剂伪影的影响。

Objective:To investigate the best of saline injection rate in CT angiography of the head and neck. Methods:Eighty-four patients were divided into three groups randomly with different intravenous injection rates,respectively,5. 0 ml/s (control group),5. 5 ml/s (experimental group 1) and 6. 0 ml/s (experimental group 2). The effect of eliminating artifacts and adverse reaction was compared. The suitable saline injection rate of CT angiography of the head and neck was analyzed. Results:The effect of eliminating artifacts in experimental group 2 (6. 0 ml/s) was better than other two group (P<0. 05). The adverse reaction among three group were no statistical significance (P>0. 05). Conclusion:Batter effect of eliminating artifacts is obtained in the CT angiography of the head and neck examination at the rate of 6. 0 ml/s.
