摘要
目的:探讨三维对比增强磁共振血管成像(3D-CEMR)对脑静脉窦血栓形成(CVST)的诊断价值.方法:对我院2005-05/2008-06诊断为CVST患者12例的影像学资料进行回顾性分析,对比3D-CE MRA和二维时间飞跃磁共振血管成像(2D-TOF MRA)对CVST的诊断价值.结果:对血栓范围、窦腔闭塞程度及侧枝静脉的显示,3D-CE MRA优于2D-TOFMRA(P<0.01);3D-CE MRA采用最大信号强度投影(MIP)联合多平面重建(MPR),曲面重建(CPR)及原始图像优于单独采用MIP(P<0.01).结论:3D-CE MR对颅内静脉窦血栓的诊断具有重要价值,多种后处理技术的联合应用能提高其诊断准确率.
Abstract
AIM:To study the diagnostic value of 3D contrast enhancement magnetic resonance angiography to cerebral venous sinus thrombosis. METHODS :To analyze retrospectively the imaging data of 12 CVST patients in our hospital from May in 2005 to June in 2008. To compare the diagnostic value to cerebral venous sinus thrombosis between 3D contrast enhancement magnetic resonance angiography and 2D TOF magnetic resonance angiography. RESULTS: 3D-CE MRA provided a superior visualization of the extent of thrombosis, degree of occlusion and collateral veins than do 2D-TOF MRA (P < 0. 01, respectively). At 3D-CE MRA, MIP images combined MPR、CPR and source images were superior to only using MIP images(P<0.01, respectively). CONCLUSION: 3D contrast enhancement magnetic resonance angiography is significant to the diagnose of cerebral venous sinus thrombosis. The combination of multiple postprocessing display modalities can elevate the diagnostic accurate rate.
