Normal computed tomography and magnetic resonance imaging anatomy of the globe, orbit, and visual pathways.
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.
