MRI and CT: Which is which, why to order, and when

摘要

Neuroimaging has evolved tremendously over the last few decades and has changed the evaluation of neuro-ophthalmic conditions. This manuscript provides an overview of orbital and intracranial imaging (e.g., conventional computed tomography (CT) and magnetic resonance (MR) scanning); will review two special sequences (i.e., fat suppression and fluid attenuation inversion recovery); and will summarize recommendations for imaging in neuro-ophthalmology.
