| 中文摘要: |
| 目的 探讨椎基底动脉延长扩张症(VBD)CT平扫的诊断价值。方法 复习815例门诊病人头颅CT平扫结果,测量其中可显示的基底动脉(BA)的直径、分出大脑后动脉的高度及走行位置,检出符合Smoker等定义的VBD病例。结果 815例中常规10mm扫描670例能清楚显示BA,30例5mm脑干靶扫显示BA28例,共发现4例符合Smoker等定义的VBD的病例,其CT与临床表现与文献报道相似。结论 常规头颅CT平扫82.2%、脑干靶扫93.3%可显示BA,对其进行测量可以诊断VBD。 |

| Objective To enhance the understanding of vertebrobasilar dolichectasia(VBD) on conventional CT scan. Methods The diameter, the height of the bifurcation and transverse position of the BA on conventional brain CT of 815 outpatients were measured to find out VBD cases according the definition of Smoker, et al. Results The BA could be displayed in 670 out of 815 on conventional CT scan. Four VBD cases acorded with the diagnostic criteria outlined by Smoker, et al, and the CT findings and clinical trends were similar to those reported in the literatures. Conclusion The diagnosis rate of BA showed clearly was 82.2% on conventional CT scan and was 93.3% on a scan of brain stem. |
