磁共振3D-BRAVO增强成像在脑静脉窦血栓中的诊断价值

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.

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

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.
