Magnetic Resonance Imaging (MRI) of the Eye and Orbit

TLDR: The contents of the orbit and its osseous margins have been particularly well imaged since the development of x-ray computed tomographic (CT) imaging as mentioned in this paper, which has the potential to provide fine structural detail and tissue characterization in this region, while avoiding ionizing radiation to the globe and providing some unique information.

Abstract: The contents of the orbit and its osseous margins have been particularly well imaged since the development of x-ray computed tomographic (CT) imaging. The greatly differing x-ray attenuation characteristics of the constituent tissues allow their separation and segregation into discrete compartments (11). Magnetic resonance imaging (MRI) is a newly emerging technique that may supplant or supplement CT for diagnostic imaging. MRI also has the potential to provide fine structural detail and tissue characterization in this region, while avoiding ionizing radiation to the globe and providing some unique information. The present discussion reflects our initial experience in examination of the eye, orbit, and structures therein by using this evolving imaging technology.
