目的探讨低场强MRI对脑膜瘤的诊断价值。方法回顾性分析经病理证实的脑膜瘤16例的MRI表现。结果T1WI为灰质等或略低信号,T2WI为等或略高信号,增强扫描病灶显示大多数为均匀明显强化。结论MRI检查对脑膜瘤定位、定性准确,平扫大部分可以确诊,特殊病例增强扫描可以提供更多信息,提高诊断率。 Objective To investigate the diagnostic value of low field strength MRI for meningioma. Methods The MRI findings of 16 cases of meningioma proved by pathology were retrospectively analyzed. Results T1WI gray contour or slightly lower signal, T2WI equal or slightly higher signal, enhanced scan showed most of the lesions were significantly enhanced. Conclusion MRI examination of meningioma location, qualitative and accurate, most of the plain scan can be confirmed, special cases enhanced scan can provide more information to improve the diagnostic rate.
