Abstract
Magnetic resonance imaging MRI using fast sequences with subjects staring at a target can provide motionfree ocular images and small receiver surface coils make it possible to produce ocular images with high spatial resolution MRI using halfFourier singleshot rapid acquisition with a relaxation enhancement sequence as a fast T2weighted imaging yields useful images for the morphologic diagnosis of ocular diseases and MRI using a fast spoiled gradientrecalledecho sequence as a T1weighted imaging yields additional information by the administration of gadoliniumbased contrast material for assessing the vascularity of intraocular tumors These ocular imaging techniques are useful for the evaluation of patients with angle closure glaucoma congenital abnormality of ocular globes intraocular tumors and several types of detachments as well as patients after ocular surgery In this pictorial essay we demonstrate the clinical applications of fast highresolution ocular MRI with fixation of the subjects’ visual foci
