摘　　要：目的探讨64排螺旋CT血管造影(CTA)在头颈血管病变临床诊断中的应用价值。方法回顾性分析该院收治的27例行64排螺旋CT血管造影检查患者的临床资料,扫描后的数据在工作站使用不同的后处理技术进行血管后重建。结果 27例行64排螺旋CT血管造影检查患者中,发现CTA检查结果正常者4例,异常者23例,其中一侧椎动脉全程均匀性变细11例,动脉起点变异7例,动脉瘤5例。共检出动脉狭窄42段,其中动脉轻度狭窄12段(28.6%),中度狭窄16段(38.1%),重度狭窄9段(21.4%),完全闭塞5段(11.9%)。后处理图像质量优23例(85.2%),良2例(7.4%),差2例(7.4%),后处理图像质量优良率为92.6%。结论 64排螺旋CT血管成像技术对诊断头颈部血管病变具有重要的临床价值,可以直观、立体的显示血管情况并能运用各种先进技术对血管情况进行多角度分析,为临床治疗提供科学的依据。因此,可作为一种安全有效的检查方法在临床进一步推广使用。Objective 64 row spiral CT angiography （CTA） in head and neck vascular lesions in clinical diagnosis application value. Methods A retrospective analysis of our hospital 27 cases of 64 row helical CT angiography in patients with clinical data, the scanned data in the workstation using different processing technique for vascular reconstruction. Results 27 cases of64row helical CT angiography in patients with CTA, found that normal examination results in 4 cases,23 cases were abnormal, one side full uniform thin vertebral artery in 11 cases, the artery origin variation in 7 cases,5 cases of intracranial aneurysm. There were42segment artery stenosis, wherein the artery with mild stenosis12, moderate stenosis （28.6%）,moderate stenosis 16 segments （38.1%）,severe stenosis 9 segments （21.4%）, total occlusion in 5 segments （11.9%） total occlusion. After processing the image quality was excellent in 23 cases（85.2%）, good in 2 cases （7.4%）,poor in 2 cases（7.4%）, after processing the image quality the excellent and good rate was 92.6%. Conclusion 64 slice spiral CT angiography in diagnosis of head and neck vascular disease has important clinical value, can be intuitive, stereoscopic display vascular and can use various kinds of advanced technology on the vessel were analyzed, providing scientific basis for the clinical treatment of. Therefore, can be used as a safe and effective method of examination in clinical further to promote the use of.
