To explore the diameter of internal carotid artery by arterial phase imaging of multi-slice spiral computed tomography (CT).
A total of 260 routine brain CT scans of the examiner were performed. And the arterial phase images of carotid artery were acquired, observed and measured through a three-dimensional reconstruction workstation. On the diameters of target sections were measured on the multiplanar reconstruction (MPR) images of carotid artery. Two groups were categorized according to gender and 3 groups by age (25 - 40 yr, 41 - 60 yr and 61 - 85 yr) for statistical analysis.
The diameter data of internal carotid artery had statistical significances among genders and 3 age groups (P < 0.05).
The diameter of internal carotid artery may be evaluated by the arterial phase imaging of multi-slice spiral CT so that the reference data can be provided for clinical diagnosis.
通过多层螺旋计算机断层扫描（CT）动脉期成像探讨颈内动脉直径。
对260例受检者进行常规脑部CT扫描。通过三维重建工作站采集、观察并测量颈动脉动脉期图像。在颈动脉多平面重建（MPR）图像上测量目标节段的直径。按性别分为两组，按年龄分为三组（25 - 40岁、41 - 60岁和61 - 85岁）进行统计分析。
颈内动脉直径数据在性别和三个年龄组之间具有统计学意义（P < 0.05）。
多层螺旋CT动脉期成像可用于评估颈内动脉直径，为临床诊断提供参考数据。
