摘　　要：目的:探讨320排CT静脉造影及其不同后处理方法对观察枕窦的可靠性及临床价值。方法:本研究回顾性分析2014-2015年之间在我医院320排CT行头颅CTV检查的140例(其中男性82例,女性58例,年龄60±15岁)患者的影像学资料。分别应用VR和MPR技术对140例患者的枕窦进行观察,测量枕窦的直径,并统计其显示率。结果:枕窦直径值为3.32±1.96cm;单独使用VR时,140例患者中的29例(20.7%)的枕窦得到显示,而VR结合MPR使用时,77例(55%)的枕窦可被显示。不同性别的枕窦显示率没有显著差异(P>0.05),但50岁以上患者枕窦的显示率(59.3%)高于50岁以下的患者(40.6%),(P<0.05)。结论:320排CTV是一种显示枕窦解剖的可靠检查方法,VR结合MPR使用可以明显提高枕窦的显示率及细微解剖判断的准确性。Purpose： To observe the anatomy of occipital sinus （OS） by 320-detector CT venography （CTV） with VR and MPR post-processing technique. Methods： We retrospectively reviewed the imaging data of 140 patients in our hospital from 2014 to 2015. All the patients were received CTV examination using 320-detector CT system. The OS was observed by VR and MPR technique respectively, and the display rate and diameter of the OS were assessed. Results： The diameter of the OS was 3.32±1.96cm. The OS was identified in 29 （20.7%） of the 140 patients by VR, while it was identified in 77 （55%） by combining VR and MPR. No significant difference was shown between different gender groups （P〉0.05）. But the OS was observed more common in over 50 years age group （P〈0.05）. Conclusion： 320-detector CTV is a reliable technique to display the anatomy of OS, and the combination of VR and MPR has more advantages in observing the OS.
