The role of MRI scanning in neuro-ophthalmology

Abstract

The role of high resolution magnetic resonance imaging (MRI) in the assessment of optic atrophy, chiasmal compression, and posterior fossa lesions is demonstrated. Good spatial resolution, absence of bony artifact and multiplanar imaging are significant advantages over CT scanning in these areas, as is the ability to detect areas of demyelination. Orbital MRI offers future potential but at present we think that CT scanning provides better spatial resolution and is more cost effective for the orbit.
