The Effects of Nuclear Magnetic Resonance Imaging on Ocular Tissues

Radiofrequency Energy-Induced Heating During MR Procedures: A Review

“…An investigation conducted by Sacks et al (64) revealed that there were no discernible effects on the eyes of rats caused by MR procedures performed at RF energy levels that far exceeded typical levels used in the clinical setting. However, as previously indicated, it may not be acceptable to extrapolate data from laboratory animals to human subjects.…”

Magnetic resonance imaging: An emerging technique for the diagnosis of ocular disorders

“…Some diagnosticians feel that MRI is now superior to CT techniques [2][3][4][5][6], due to MRI's increase in sensitivity and higher resolution, as well as its lack of known hazards to the patient [7][8][9]. The introduction and use of surface coils, higher field strength magnets, new pulse sequences and shielded gradients are a few of the major factors responsible for this judgment.…”
