目的：探讨MRI及MRV在脑静脉和静脉窦血栓( CVST)形成中的诊断价值。方法回顾性分析16例CVST患者的临床和影像资料。16例患者均经MRI平扫及2D-PC法MRV扫描,12例患者行MRI增强扫描。结果11例患者中CT平扫可见直接或间接征象。 MRI平扫可见受累静脉窦流空信号消失,静脉窦内信号不均,15例出现静脉性脑梗死表现,其中2例合并出血。增强扫描7例患者受累静脉窦表现为“空三角征”。 MRV表现为受累静脉窦不显影或局限性信号缺失、中断。结论 MRI结合MRV是诊断CVST高度敏感、无创、有效的方法。

Objective To investigate the diagnostic value of MRI and MRV for the cerebral venous and sinus thrombosis( CVST ) . Methods The clinical and imaging data were retrospectively analyzed in 16 cases of proved CVST. All patients had done MRI and 2D-PC MRV, and 14 cases had done CT scan. Results Eleven cases CT scan showed direct or indirect signs. Conventional MRI showed that the flow void signal of the venous sinus disappeared, and abnormal signals were found. 15 cases had venous infarction in brain parenchyma, 2 cases of which were combined with hemorrhage. Contrast enhanced MRI showed empty triangle sign. MRV showed that involved venous sinus was non-visualized or localized signal was missing and interrupted. Conclusion Conventional MRI combined with MRV is highly sensi-tive, noninvasive and effective in the diagnosis of CVST.
