64层螺旋CTA在缺血性脑血管病中的应用价值

Application of 64-slice spiral CT angiography in ischemic cerebral vascular disease

目的:探讨64层螺旋CT血管造影(CTA)在缺血性脑血管病(ICD)中的应用价值。方法:收集50例拟诊脑梗死的患者,同时进行64层螺旋CTA和DSA检查,将64层螺旋CTA和DSA结果进行对照。结果:以DSA为金标准,CTA检出脑梗死患者头颈部动脉狭窄的敏感度为97.8%,特异度为76.4%。结论:64层螺旋CTA能够清晰地显示头颈部动脉的狭窄,可作为DSA诊疗前重要的筛查技术。

Objective： To explore the clinic application of 64--slice CT angiography （CTA） in isehemic cerebral vascular disease. Methods..A total of 50 Patients, clinically diagnosed as acute cerebral infarction, were examined by 64--slice CTA and DSA. The results of CTA were compared with DSA. Results：In patients with acute cerebral infartion, CTA sensitivity and specificity for detecting internal cerebral artery stenosis were 97. 8 M and 76.4 %, respectively. Conclusion： 64--slice CTA can clearly demonstrate changes in internal cere- bral and carotid artery stenosis and can be an important screening technique before the diagnosis and therapy of DSA.
