MR imaging of the globe and optic nerve.
The superb contrast resolution of MR imaging has significantly improved radiologists' ability to evaluate the anterior visual pathways and globe. Optimal imaging of the orbit requires the radiologist to have a working understanding of the clinical questions the ophthalmologist needs answered. In this article, basic orbit anatomy, MR imaging protocols for the orbit, and common clinical scenarios encountered when imaging the orbit are reviewed, with a focus on the optic nerve and globe.
