脑血流彩色全循环成像对脑静脉窦血栓形成诊断评价的研究

目的 探讨脑血流彩色全循环成像对脑静脉窦血栓形成的诊断价值。方法 对我科收治的10例重症脑静脉窦血栓形成的患者，应用西门子Artis zee biplane双平板DSA，所配设备System syngo X-WP三维后处理工作站，将DSA二维原始序列数据用Iflow软件分析处理，在一张图像上分别用红色、淡蓝色、深蓝色标记显示一侧颈内动脉或一侧椎动脉的全程血流情况。结果 利用Iflow软件处理后能在同一张影像上显示脑血流彩色全循环图像，清晰显示血管走向、狭窄、闭塞等病变，可以自动计算出循环不同期血流达峰时间，帮助诊断、评估脑血流动力学变化及指导治疗。结论 脑血流彩色全循环成像对脑静脉窦血栓形成的诊断有较大临床应用价值，可用于评估脑血流动力学变化，是影像诊断学的新方法。

Value of cerebral blood flow images of color full cycle to diagnosis of cerebral venous sinus thrombosis

Objective To investigate the value of cerebral blood flow images of color full cycle to the diagnosis of cerebral venous sinus thrombosis. Methods DSA two-dimensional raw sequence data of cerebral blood vessels which were acquired from 10 patients with severe cerebral venous sinus thrombosis were analyzed and processed by Iflow software of System syngo X-WP three-dimensional post-processing workstation provided by Siemens Artis zee biplane twin flat DSA in order to attain the one side internal carotid artery or one side vertebral artery full process blood flow images marked by red, light blue, and dark blue. Results The color full cycle images of cerebral blood flow which were successfully attained clearly showed vascular run, narrow and occlusion. The cycle time reached to the peak of blood flow at different phase, which were antomatically calculated, helped the doctors to assess the cerebral blood flow dynamics, and diagnose and treat cerebrovascular disease. Conclusions The color full cycle images of the cerebral blood flow, which is of great clinical value to the diagnosis of the cerebral venous sinus thrombosis and used for the assessment of changes in the cerebral hemodynamics, is a new method to diagnose the cerebrovascular disease.
