脑静脉窦血栓形成的MRI和MR静脉成像表现特征

目的探讨MRI和MR静脉成像(MRV)在脑静脉窦血栓形成中的诊断特征。材料与方法 14例脑静脉血栓形成患者都经MRI 平扫和2D-PC法MRV。结果 14例脑静脉血栓形成中,MRI SE序列确诊11例,3例急性早期MRI平扫漏诊,后经MRV确诊。MRI表现静脉窦内短T1、长T2信号,血栓形成的静脉窦闭塞、充盈缺损。结论 MRI与MRV联合检查是诊断CVST的一种最佳方法,MRV是当前无创性、准确、敏感、理想的诊断脑静脉窦血栓形成的重要补充方法。

MRI and MRV features of cerebral venous sinus thrombosis

Objective： To discuss characteristics of cerebral venous and sinus thrombosis （CVST） in the MRI and MRV diagnosis. Materials and Methods： Collection 14 cases with CVST, all patients had done MR SE sequence, had done 2D-PC MRV. Results： 14 cases with CVST, MR SE sequence diagnosed 11cases, 3 cases were acute early because of MRI misdiagnosis, but later diagnosed by MRV. MR performs short T1 and long T2 signs of the Venous Sinus, MRV performs the thrombosis of Venous Sinus in the way of block, filling defect. Conclusions： To combined MRI and MRV that is the best of method for the CVST. MRV is one of noninvasive, accurate, sensitive and ideal important added methods for the diagnosis of cerebral venous sinus thrombosis nowadays.
