【摘要】 目的总结磁共振静脉血管成像对颅内静脉窦病变的应用价值。方法影响静脉窦的病变共35例,包括脑膜瘤19例,转移瘤2例,静脉窦血栓形成12例,后颅窝硬膜外血肿2例,均行MRV检查。结果 21例颅内肿瘤中,MRV显示11例静脉窦受压移位,6例静脉窦狭窄,4例静脉窦闭塞,MRV与手术结果符合率约90.5%。静脉窦血栓形成时MRV表现为静脉窦显影中断、狭窄和引流静脉的扩张,比常规MRI多检测出4处病变。MRV能显示硬膜外血肿造成的静脉窦狭窄、移位。结论 MRV能较好显示静脉窦异常,对指导治疗有意义。更多还原

【Abstract】 Objective To study the value of magnetic resonance venography (MRV) in the anomalies of cranial venous sinus. Methods 35 cases with cranial lesions, including meningioma in meningioma(n=19 cases), metastasis(n=2 cases), cerebral venous sinus thrombosis(n=12 cases), epidural hematoma in the posterior fossa(n=2 cases) were all performed MRV examinations. Results In 21 cases with cranial tumors, MRV showed venous sinus shift in 11 cases, venous sinus stenosis six in 6 cases, venous sinus completely occlusion in 4 cases , MRV consistented with operative findings at the rate of about 90.5%. MRV image of cerebral venous sinus thrombosis show venous sinus interrupted, narrow, and expansion of the draining veins￡MRV found 4 lesions more than MR routine sequences. Shifted, narrow sinuses caused by extradural hematoma could be demonstrated on MRV. Conclusion MRV can display the sinus abnormalities which is valuable to guide clinical treatment.更多还原
