The optic canal is medial to the superior orbital fissure within the lesser wing of the sphenoid bone. A narrow segment of bone, the optic strut, separates the optic canal from the superior orbital fissure. The inferior orbital fissure extends anteriorly and laterally between the lateral and inferior orbital walls. The inferior orbital fissure connects the orbit to the pterygopalatine fossa posteriorly and the infratemporal fossa anteriorly. The maxillary division of CN V leaves the cranium through the foramen rotundum into the pterygopalatine fossa and then travels into the orbit through the inferior orbital fissure.

Current CT scanners administer a dose of radiation of approximately 1-2 centi-Gray (cGy) per scanning plane. By comparison, a posteroanterior and lateral chest radiograph administers a dose of radiation of approximately 5 milli-Gray (mGy). The visualization of tumors that are highly vascular (eg, meningioma) or those with altered vascular permeability is improved by the use of intravenous contrast-enhancing agents. CT has resolution and tissue-contrast capabilities allowing imaging of soft tissues, bones, contrast -containing blood vessels, and foreign bodies.
