Findings of Retinues on Gadolinium-Enhanced Turbo Fluid-Attenuated Inversion Recovery Images

Abstract

Of the sequences studied, gadolinium-enhanced tFLAIR images were found to be the best in identifying incidental retinitis and diabetic retinopathy discovered on routine brain magnetic resonance imaging examinations.

Evaluation of MRI for in vivo monitoring of retinal damage and detachment in experimental ocular inflammation

“…The eye structure visualized by MRI between vitreous humor and sclera has been called the retina/choroid complex in some studies (12, 13) and retina in others (11, 19); the latter term (retina) is used in the present study. This difference in terminology arises from the fact that the choroid is very thin.…”

“…All these values are below the resolution of the in vivo and ex vivo ocular MRI techniques with which the rat retina was visualized (11, 13). Thickness of the choroid of normal human eyes is several times greater; however, human MRI techniques have poorer resolution (12, 19) and hence the choroid has not yet been visualized in humans or animals by MRI. Despite this, these studies demonstrated the potential of MRI to visualize in vivo the retina (retina/choroid complex).…”

“…In an MRI study reported in the literature (19), values of TRET larger than 1.2 mm were measured on MR images of five patients with retinal abnormalities and compared with the values of TRET measured in five normal subjects. According to this study, the upper limit for the normal human retinal thickness is 1.2 mm.…”

3-Dimensional Magnetic Resonance Imaging of the Freely Moving Human Eye

“…Eye structures, such as the retina, iris, ciliary body, lens and aqueous and vitreous humours as well as surrounding tissues, such as muscles, in humans or animals can be visualized in vivo (Fanea and Fagan, 2012), reaching the retina resolution in animals Shen et al, 2006). Anatomic information coming from T2-weigthed or T1-weighted mapping can identify retinal detachment (Deans et al, 1988) and retinal abnormalities (Bahn et al, 1998), as well as variations in eye volume, surface area and shape in animals (Tkatchenko et al, 2010) and humans (Lim et al, 2011).…”

High‐resolution MRI of uveal melanoma using a microcoil phased array at 7 T

“…High‐resolution MRI is developing as a promising tool for ocular imaging in terms of detailed structures , pathological conditions , non‐invasive blood flow measurements , natural ageing and, potentially, for intraocular lens surgery . The versatility of MRI, combined with the fact that it is a non‐contact technique, make it a valuable additional imaging modality to, for example, optical coherence tomography (OCT) and ultrasound.…”
