| 摘 要： | 目的探讨多层螺旋CT平扫对椎基底动脉延长扩张症(VBD)的诊断价值。方法复习2658例病人头颅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2658例全部按常规8mm多层CT容积扫描并行3mm重建,2379例能清楚显示BA,共发现16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。结论头颅多层螺旋CT平扫后行3 mm重建图像89.50%可显示BA,对其进行测量可以诊断VBD。

| Abstract: | Objective This study was designed to explore the value of multi-slice spiral CT in the diagnosis of vertebrobasilar dolichectasia(VBD).Methods The diameter,the bifurcated height and transverse position of basilar artery(BA) on multi-slice spiral brain CT images of 2658 patients were measured to find out vertebrobasilar dolichectasia cases by according to the definition of WR Smoker,et al.Results The basilar artery could be demonstrated clearly in 2379 out of 2658 on multi-slice spiral CT images which were obtained by reconstruction at 3mm slice thick using images of 8mm slice thick.16 vertebrobasilar dolichectasia cases accorded with diagnostic criteria outlined by WR Smoker et al were found,and the CT finding and clinical representations were similar to those reported in the literatures.Conclusion 89.50 % basilar artery could be displayed on multi-slice spiral brain CT images according to the methods mentioned,then vertebrobasilar dolichectasia could be diagnosed. |
