    摘要目的：分析脑膜瘤MRI的影像学特点，以提高脑膜瘤的诊断水平。方法：收治脑膜瘤患者25例，对其临床资料进行回顾性分析。结果：脑膜瘤在T1WI图像表现均一的低信号10例或等信号15例；在T2WI图像呈稍高信号18例或等信号4例；增强后呈均匀强化者23例。结论：脑膜瘤的MRI表现具有特征性，MRI对脑膜瘤的定位、定性诊断具有明显的价值，可明显提高诊断准确率。

    AbstractObjective：To analyze the features of MRI of meningioma in order to improve the level of diagnosis of meningioma. Methods：25 cases with meningioma were selected.The clinical data were retrospectively analyzed.Results：T1WI image of meningioma showed low signal in 10 cases or equal signal in 15 cases.T2WI image showed slightly high signal in 18 cases or equal signal in 4 cases.There were 23 cases with homogeneous enhancement signal after the enhancement.Conclusion：There are characteristics of MRI features of meningioma.MRI has obvious value for orientation ......
