摘　　要：目的:探讨磁共振静脉血管成像(MRV)对上矢状窦旁脑膜瘤的临床应用价值.方法:对15例上矢状窦旁脑膜瘤的MRV图像进行分析,观察瘤体对上矢状窦的压迫、侵蚀和闭塞程度,并与手术结果对照分析.结果:15例上矢状窦旁脑膜瘤中,6例瘤体与一侧静脉窦壁外层附着,5例瘤体侵蚀静脉窦,4例瘤体长入上矢状窦内,窦腔完全闭塞,MRV所示与手术病理结果完全相符.结论:MRV对上矢状窦旁脑膜瘤与上矢状窦关系的显示十分敏感,能够精确提供上矢状窦旁脑膜瘤的手术治疗信息.Objective： To investigate the clinically applied value of MR venography（MRV） for diagnosing parasagittal meningioma. Methods： Observing the degree of compression, erosion and obstruction to superior sagittal sinus from parasagittal meningioma by analyzing the images of MRV of 15 cases. The diagnosis of MRV was compared with the findings in operation. Results ： 6 cases of neoplasm adhering to the outer layer of venous sinus, 5 cases eroding it, 4 cases growing into and blocking it completely on the images of 15 cases. All these manifestations on the images were identical with the findings in operation. Conclusion： The images of MRV of parasagittal meningioma can reveal the relations between neoplasm and superior sagittal sinus accurately and provide detailed evidence for operation.
