【摘要】 目的:探讨脑膜瘤MRI征象与病理关系。方法:28例经手术证实的脑膜瘤与病理对照分析。结果:28例脑膜瘤中包膜完整16例,瘤周水肿24例;硬膜“尾”征20例;均匀强化20例;瘤内出现砂粒体20例;瘤内出现血管流空信号4例。结论:MRI某一征象要确定脑膜瘤的病理分型无明显相关性,但综合考虑各种MRI征象,可以提示某种病理型脑膜瘤。更多还原

【Abstract】 Objective:To study the relationship between MRI features and pathological types.Materials and Methods:MRI features of 28cases with meningiomas were compared with their pathological findings.Results:Sixteen cases had their integral capsules.Peritumor edema was found in24cases.Dural"tail"sign was present in24cases.Twenty cases appeared homogeneous enhancement.Psammoma-bodies in the tumors were found in20cases.Vascular flow void features in the tumor was seen in20cases.Conclusion:There is no correlative relationship between only one certain sign of MRI and the patho-logic classification.However combination of several MRI features could be used to figure out the pathologic type of menin-gioma by a comprehensive analysis.更多还原
