摘　　要：目的探讨3D-T1增强及CE-MRV序列对颅内静脉窦血栓显示的价值。方法回顾性分析我院2015-2020年临床诊断颅内静脉窦血栓(CVST)的患者49例,这些患者均进行3D-T1增强及CE-MRV扫描,对于不同序列的诊断价值进行评估。结果49例患者中3D-T1增强显示49例血栓,CE-MRV显示45例血栓。用两种方法分别测量血栓的长度,其中3D-T1增强测得的血栓长度约22.22mm±13.08mm,CE-MRV测得的血栓长度约19.21±13.18mm,P﹤0.05,差异具有统计学意义,对血栓进行分段研究,3D-T1增强显示上矢状窦血栓28例,下矢状窦3例,横窦41例,直窦13例,乙状窦41例;CE-MRV显示上矢状窦血栓26例,下矢状窦血2例,横窦35例,直窦10例,乙状窦36例,分别测得血栓长度的平均值,其中下矢状窦、横窦、直窦及乙状窦差异具有统计学意义,在3D-T1增强中能显示出CVST的并发症-硬脑膜动静脉瘘为0例,CE-MRV显示硬脑膜动静脉瘘5例,差异具有统计学意义。结论3D-T1增强对于颅内静脉窦血栓的显示较CE-MRV更加准确、全面,但是仅CE-MRV能显示出CVST较为严重的并发症-硬脑膜动静脉瘘,因此临床工作中应将CE-MRV与3D-T1增强相结合更有诊断价值,二者缺一不可。Objective The aim of this article is to determine whether a combination of CE-MRV and 3D-T1 enhancement sequences can help to identify dural venous sinus thrombosis(DVST)with greater accuracy.Methods A total of 49 patients with DVST underwent,CE-MRV and 3D-T1 enhancement from 2010 to 2019 In the First Affiliated Hospital of Anhui Medical University.Two experienced observers(Vice senior title or above)interpreted the images retrospectively for the presence of DVST.The diagnostic value of different sequences was evaluated.Results Among the 49 patients,49cases showed thrombus on 3D-T1 enhancement and 45 cases on CE-MRV.The length of thrombus measured by 3D-T1 was about 22.22mm±13.08mm,the length of thrombus measured by CE-MRV was about 19.21±13.18mm,P﹤0.05,and the difference was statistically significant.The thrombus was studied by segments.3D-T1 enhanced showed 28 cases of superior sagittal sinus thrombus,3cases of inferior sagittal sinus thrombus,41 cases of transverse sinus thrombus,13 cases of straight sinus thrombus,41 cases of sigmoid sinus thrombus;ce-mrv showed 41 cases of superior sagittal sinus thrombus There were 26 cases of sinus thrombosis,2 cases of inferior sagittal sinus blood,35cases of transverse sinus,10 cases of straight sinus and 36 cases of sigmoid sinus.The average length of thrombosis was measured respectively.The difference of inferior sagittal sinus,transverse sinus,straight sinus and sigmoid sinus was statistically significant.In 3D-T1 enhancement,the complication of CVST dural arteriovenous fistula was 0 case,and ce-mrv showed dural arteriovenous fistula in 5cases.The difference was statistically significant.Conclusion The combination of,enhancement may allow the diagnosis of DVST,but only can show dural arteriovenous fistula,a serious complication of CVST.Therefore,it is more valuable to combine CE-MRV with 3D-T1 enhancement in clinical work.
