摘要
目的研究磁共振静脉血管成像(MR Venography,MRV)术前评估脑膜瘤与静脉窦关系的价值。材料与方法对26例静脉窦旁脑膜瘤的相位对比法MRV图像进行分析,观察静脉窦与脑膜瘤的位置关系,同时观察瘤体对静脉窦的压迫、侵蚀及闭塞程度,并与手术结果进行逐一对照分析。结果 26例患者相位对比法MRV图像均显示清晰:(1)11例提示静脉窦不同程度受压,手术证实11例静脉窦均受累,并与肿瘤粘连,两者符合率为100%;(2)6例肿瘤与静脉窦紧贴,手术证实4例静脉窦未见侵犯,另2例静脉窦部分受累;(3)MRV提示肿瘤与静脉窦无关系9例,手术证实9例静脉均无受累。结论相位对比法MRV作为一种经济的、无创的、无需对比剂的影像检查技术,能够评价脑膜瘤与静脉窦的关系,对静脉窦旁脑膜瘤的手术入路的选择及术后并发症的预防具有重要指导意义,值得术前常规采用。
Objective：To study the value of phase-contrast sequence MRV in evaluating relationship between meningioma and cranial venous sinus. Materials and Methods：Analyzing 26 Phase-contrast Sequence MRV images of meningioma beside venous sinus. Observing the location concern with venous sinus and the meningioma, and the degree that the tumor compressing, eroding and obstructing the venous sinus. Then, comparating and analyzing the diagnoses of MRV with the ifndings of operation one by one. Results：All of the 26 phase-contrast sequence MRV images are cleraly displayed：（1） 11 cases suggest that the venous sinus was compressed of different degree, and it was conifrmed by operation, in which it was found that the venous sinus had adhesion with the tumor, and the coincidence rate is 100%. （2） 6 cases suggest that the tumor clung to the venous sinus, four of which were conifrmed by operation that the venous sinus was not eroded, while the other two were comifrmed to be eroded. （3） 9 cases suggest that there was no relationship between the tumor and venous sinus, and it was conifrmed by operation. The coincidence rate is 100%. Conclusions：As an economical, non-invasive, non-contrast media imaging technology, phase-contrast sequence MRV has values to evaluating the relationship between meningioma and cranial venous sinus. It has important guiding signiifcance when selecting surgical approach of meningioma close to venous sinus, and preventing complication after operation. It is worth routine using before operation.
