摘　　要：目的:探讨磁共振成像(MRI)及磁共振静脉成像(MRV)对颅内静脉窦血栓形成(CVST)的诊断价值。方法:回顾性分析经临床和影像学方法确诊的14例CVST患者。MR检查技术包括平扫,增强扫描及MRV,14例均行CT平扫,其中1例行DSA检查。结果:14例CVST累及上矢状窦血栓形成4例,横窦血栓形成6例、乙状窦5例,MRI可清晰显示颅内静脉窦血栓形成的直接征象和间接征象,MRV可显示受累静脉窦不显影或者充盈缺损形成。结论:常规MRI结合MRV对颅内静脉窦血栓形成的早期诊断具有重要价值。Objective：To study the diagnostic value of MRI and MR venography（MRV）in cerebral venous sinus thrombosis（CVST）.Methods：MR findings of 14 cases of dural sinus thrombosis diagnosed by clinic and imaging were rewiewed retrospectively.All cases were underwent non-enhanced MRI,enhanced MRI and MR venography.All cases were performed CT,additionaly 1 patients was underwent DSA.Results：CVST involved superior sagittal sinus in 4 cases,transverse sinus 6 cases,sigmoid sinus 4 cases,Direct signs and indirect of CVST could be displayed by MRI,MR venography（MRV）displayed the loss of the normal flow signal,as nonvisulization or the filling defect sign in the involved cerebral venous sinuses.Conclusion：Early MRI combined with MRV has shown significant diagnostic value in the diagnosis of cerebral venous sinus thrombosis.
