Ameliorated computed tomography techniques and new magnetic resonance sequences have led to an important improvement in temporal bone imaging. Computed tomography is still the method of choice for imaging of temporal bone fractures, middle ear disease, and conductive hearing loss, although magnetic imaging can add important information. Patients with lesions of the cerebellopontine angle; internal auditory canal; inner ear; and, in general, all patients with sensorineural hearing loss, vertigo, and tinnitus are best examined with magnetic resonance imaging. In some cases, however, such as congenital malformations and petrous apex lesions, magnetic resonance imaging and computed tomography are complementary. The value of both modalities is discussed.
改良的计算机断层扫描技术和新的磁共振序列已使颞骨成像有了重要改进。计算机断层扫描仍是颞骨骨折、中耳疾病和传导性听力损失成像的首选方法，尽管磁共振成像能提供重要信息。对于桥小脑角、内耳道、内耳病变的患者，以及一般所有感音神经性听力损失、眩晕和耳鸣的患者，最好用磁共振成像进行检查。然而，在某些情况下，如先天性畸形和岩尖病变，磁共振成像和计算机断层扫描是互补的。本文讨论了这两种检查方式的价值。
