【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(P0.05),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%),(P0.05)。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。
[Abstract]:Objective: to investigate the reliability and clinical value of 320 slice CT venography and its different postprocessing methods in occipital sinus. Methods: this study retrospectively analyzed 140 cases (82 male) of head CTV in 320 row CT from 2014 to 2015 in our hospital. The imaging data of 58 female patients, aged 60 卤15 years, were observed by VR and MPR techniques, and the diameter of occipital sinus was measured. Results: the diameter of occipital sinus was 3.32 卤1.96 cm. The occipital sinuses of 77 patients with VR combined with MPR) could be displayed. There was no significant difference in the display rate of occipital sinuses between different genders (P 0.05), but the display rate of occipital sinuses in patients over 50 years old was 59.3%) higher than that in patients under 50 years old. Conclusion CTV is a kind of display. The reliable examination method of occipital sinus anatomy: VR combined with MPR can obviously improve the display rate of occipital sinus and the accuracy of fine anatomic judgment.
