摘要
目的：探讨常规磁共振成像（MRI）及磁共振静脉成像（MRV）对脑静脉窦血栓形成（CVST）的诊断价值。方法：11例CVST患者，男3例，女8例，年龄19～56岁，平均39．4岁。使用Philps NT5型0．5T超导磁共振扫描仪，常规行SE T1WI、TSE T2WI及液体衰减翻转恢复（FLAIR）序列检查，其中7例行相位对比（PC）法2D静脉血管成像。结果：MRI可清晰显示脑静脉窦血栓形成的直接征象（静脉窦流空效应消失，静脉窦内出现各期信号不同的血栓）和间接征象（脑水肿、脑梗死、脑出血等），MRV可更好地显示阻塞静脉窦。结论：常规MRI结合MRV对脑静脉窦血栓形成有较好的诊断价值。
Objective： To study the diagnostic value of MRI and MR venography （MRV） in cerebral venous sinus （CVS） thrombosis. Methods： 11 cases of cerebral venous sinus thrombosis were investigated. There were 3 male and 8 fe male patients with an average age of 39.4 years. All of the cases were studied with Philps NT5 0.5T MRI system. The SE T1WI, TSE T2WI and FLAIR sequences and phase contrast （PC） 2D venography were performed rouminely. Results：Direct signs of CVS thrombosis could be displayed by MRI, showing disappearance of flow void effect of venous sinus,various signal intensities within CVS assessed in different stages of thrombosis. Indirect signs of CVS thrombosis included cerebral edema, cerebral infarction,cerebral hemorrhage etc. Occlusion of cerebral venous sinus could be shown by MRV satisfactorily. Conclusion： MRI combined with MRV has shown significant diagnostic value in the diagnosis of cerebral venous sinus thrombosis.
