颈内动脉管径螺旋CT成像的分析

Spiral computed tomography imaging of internal carotid artery diameter：a report of 260 cases

目的探讨多层螺旋CT动脉期成像评价颈内动脉管径。方法2009年5月至2010年6月期间，在丽水市人民医院行脑血管增强扫描检查510例患者中，260例行颅脑CT增强扫描的检查者，动脉期图像经工作站三维重建颈内动脉，观察测量颈内动脉，在MPR图像上进行颈内动脉各段管径的测量，按性别分2组、按年龄分3组（25～40岁、41～60岁和61—85岁）进行统计学分析。结果男女之间、不同年龄组之间颈内动脉管径的数值及差异均具有统计学意义（均P〈0．05）。结论多层螺旋CT动脉期成像能较好评价颈内动脉的管径，为临床诊断提供参考数据。

Objective To explore the diameter of internal carotid artery by arterial phase imaging of multi-slice spiral computed tomography （ CT）. Methods 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. Results The diameter data of internal carotid artery had statistical significances among genders and 3 age groups （P 〈 0.05 ）. Conclusion 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.
