The presence of bone and fat in the orbit provide high contrast with normal structures on both CT and MR images. In patients with visual deficits or oculomotor paralysis, imaging studies should include the intracranial cavity to evaluate the visual pathways back to the occipital cortex and the cranial nerves within the cavernous sinuses and brainstem. Magnetic resonance images display the intracranial anatomy in exquisite detail. Fat-suppressed magnetic resonance sequences should be used in conjunction with gadolinium enhancement.
眼眶内的骨骼和脂肪在CT和MR图像上与正常结构形成高对比度。对于有视力缺陷或动眼神经麻痹的患者，影像学检查应包括颅内腔，以评估通向枕叶皮质的视觉通路以及海绵窦和脑干内的颅神经。磁共振图像能极其详细地显示颅内解剖结构。脂肪抑制磁共振序列应与钆增强联合使用。
