脑静脉(窦)血栓形成的MRI和MRV诊断价值简

目的探讨脑静脉血栓（CVT）和静脉窦血栓（CVST）形戍的磁共振成像（MRI）和磁共振静脉系成像（MRV）特征。方法回顾性分析经磁共振诊断和临床证实的58例脑静脉（窦）血栓病人的MRI资料，58例均行颅脑MRI平扫，其中39例行2DPC法MRV成像，分析脑静脉窦、脑静脉内和脑实质内信号改变。结朵脑静脉窦血栓49例：单独静脉窦血栓31例，合并浅静脉血栓8例、其中3例合并出血：合并脑深静脉血栓4例：同时合并深、浅静脉血栓6例。单独脑深静咏血栓9例。结论MRI结合MRV是诊断脑静脉（窦）血栓首选、最有效的无创检查方法。

The Dignosis of Cerebral Venous Sinus Thrombosis by MRI and MRV

Objiective To investigate the magnetic resonance imaging （MRI） and magnetic resonance venography （MRV） features of cerebral venous （sinus） thrombosis. Metthods Data of 58 cases of cerebral venous（sinus） thrombosis were analyzed retrospectively, which were performed by MRI and MRV and treated with clinical therapy. All of the cases were scanned by MRI, 39 of which went on cerebral venons sinus 2D PC MRV, the signal changes of cerebral venous sinus, cerebral venous and intracranial were observed and analyzed. Result There are 49 cases with venous sinus thrombosis, in which 31 cases accompanied with single venous thrombosis： 8 cases accompanied with superfacial venous thrombosis, in which 3 cases occurred henmrrbage, 4 cases accompanied with deep cerebral venous thrombosis： there are 6 cases with deep cerebral venous sinus thrombosis and superfacial cerebral venous thrombosis： Single deep cerebral venous thrombosis were 9 cases. Conclusion The combination of MRI and MRV is one of the most effective, noninvasive methods for the diagnosis of cerebral venous（sinus） thrombosis.
