MRI with gadolinium enhancement is the imaging modality of choice in the diagnosis of meningiomas. Various MRI features are described. MRI signal intensity characteristics in meningiomas contain information that could be correlated with the histopathology of the tumor. Hyperintensity on T2-weighted images indicates soft tumor consistency and microhypervascularity and is more often seen in aggressive, angioblastic, or meningothelial meningiomas. MRI is useful in demonstrating dural sinus involvement. Meningiomas in unusual locations and their mimics are also presented.
钆增强磁共振成像（MRI）是诊断脑膜瘤的首选成像方式。文中描述了各种MRI特征。脑膜瘤的MRI信号强度特征包含与肿瘤组织病理学相关的信息。T2加权图像上的高信号表明肿瘤质地柔软且存在微血管增多，在侵袭性、血管母细胞性或脑膜内皮性脑膜瘤中更常见。MRI有助于显示硬脑膜窦受累情况。还介绍了罕见部位的脑膜瘤及其类似病变。
