Methods The vertebral arteries of twelve cases underwent 16-slice spiral CT angiograph.

多层螺旋CT的面世和临床应用，在一定程度上弥补了此种不足[1-4]。

Methods forty patients with head/neck 16 slice CT angiograph were divided into two groups at random,each group has 20 cases, the plain scan and the CTP was performed before CTA to all 40 cases. Group A use CTP to obtain the peak time of contrasted artery as CTA delay time, and scan from head side to foot side. Group B use contrast media automatic bolus tracking to obtain delay time,scan from foot side to head side.two groups CTA images were collated.

使用16排螺旋CT对40例患者行头颈部CTA检查，随机分为两组，各20例，所有患者在CTA之前行脑CT平扫及脑CT灌注扫描，A组以CTP所显示的动脉峰值时间作为CTA的延迟时间，扫描方向为自头侧向足侧。B组使用造影剂浓度实时监控跟踪触发技术确定延迟时间，扫描方向自足侧向头侧扫描，两组CTA图像相对照。

The contrast material was bolus injected through antecubital vein ,while four layers of dynamic scans were performed for 50 seconds.These slice dynamic images were processed with the CT perfusion software package.Cerebral blood flow,cerebral blood volume,and mean transit time were measured within the specific regions of interest of the brain,and quantitative analysis was performed.

在常规轴面CT扫描后选取基底节及其相邻层面，经肘静脉团注对比剂，同时开始连续50 s的四层动态扫描，重建的198幅动态图像使用CT脑灌注软件包进行处理，获得灌注图像，测量所选脑内感兴趣区的血流量、血容量及平均通过时间，并对其进行定量分析。
