High-resolution 3D MRI of the skull base allows for a more detailed and accurate assessment of normal anatomic structures as well as the location and extent of skull base pathologies than has previously been possible. This article describes the techniques employed for high-resolution skull base MRI including pre- and post-contrast constructive interference in the steady state (CISS) imaging and their utility for evaluation of the many small structures of the skull base, focusing on those regions and concepts most pertinent to localization of cranial nerve palsies and in providing pre-operative guidance and post-operative assessment. The concept of skull base compartments as a means of conceptualizing the various layers of the skull base and their importance in assessment of masses of the skull base is discussed.
与以往相比，高分辨率的颅底三维磁共振成像（MRI）能够对正常解剖结构以及颅底病变的位置和范围进行更详细、准确的评估。本文介绍了高分辨率颅底MRI所采用的技术，包括对比剂增强前后的稳态构成干扰序列（CISS）成像，及其在评估颅底众多微小结构方面的应用，重点关注与颅神经麻痹定位最相关的区域和概念，以及在提供术前指导和术后评估方面的作用。文中还讨论了颅底分区的概念，这是一种将颅底各层概念化的方法，以及其在评估颅底肿物中的重要性。
