磁共振3D-BRAVO增强成像在脑静脉窦血栓中的诊断价值

Diagnostic Value of MRI 3D-BRAVO Enhanced Imaging in Cerebral Venous Sinus Thrombosis

目的探讨对比磁共振平扫、MRV、常规增强及3D-BRAVO增强成像等各序列在显示颅脑静脉窦血栓病变能力的差异,3D-BRAVO增强成像序列对颅脑静脉窦血栓的诊断价值.方法回顾性分析经临床诊断脑静脉窦血栓患者29例,所有患者均行常规T1WI、T2WI、FLAIR、MRV、常规增强及3D-BRAVO增强成像.结果在29例脑静脉窦血栓(cerebral venous sinus thrombosis,CVST)患者中,常规平扫、常规增强显示12例静脉窦血栓,MRV显示13例静脉窦血栓,3D-BRAVO增强成像显示全部29例.结论在CVST患者中,3D-BRAVO增强序列可较常规序列成像更清楚地显示脑内静脉窦病灶,可极大程度提高早期诊断CVST,为临床制定治疗方案及评估预后提供最直观的影像学证据.

Objective To explore the diagnostic value of 3 D-BRAVO enhanced imaging in cerebral venous sinus thrombosis（CVST） by comparing the results of conventional imaging and 3 D-BRAVO enhanced imaging.Me thods Retrospective analysis was conducted to analyze the imaging results of 29 cases diagnosed with CVST.All the cases were scanned with T1 WI,T2 WI,FLAIR,MRV,conventional enhanced and 3 D-BRAVO enhanced imaging.Re s ults CVST were found in 12 cases with conventional scan and conventional enhanced imaging, 13 cases with MRV and all the 29 cases with 3 D-BRAVO.Conclus ion The technology of 3 D-BRAVO enhanced imaging could provide better detectionresult, which significantly improve early diagnosis of CVST and provide intuitive imaging evidence for clinical treatment and prognosis evaluation.
