Advanced MR imaging of the visual pathway

Objectives:
The vision is a highly complex sense, which derives from not only the orbit and globes but also deep within the
intracranial compartment. MRI, through its variety of sequences, offers a dynamic array of structural and functional imaging tools
to investigate and characterize this system. Our goal is to describe several advanced MRI sequences, and to explore their potential
clinical applications as well as areas for further development.
Learning Points:
MRI imaging of the visual pathway will be reviewed, with a focus on the following sequences: Structural and
functional retinal MRI may be utilized in the assessment of diabetic retinopathy as well as glaucoma; Optic nerve MR, with diffusion
weighted imaging (DWI) andmagnetization transfer ratio (MTR), which demonstrate potential clinical applications in acute ischemia
and monitoring demyelination, respectively; high resolution MRI of the lateral geniculate nucleus (LGN) offers the ability to delineate
pathology affecting this vital thalamic nucleus. Further improvements in in-plane resolution may augment correlations with clinical
deficits through retinotopic mapping. Optic radiation diffusion tensor imaging (DTI), including the utilization of tractography in
pre-operative/therapeutic planning for tumors and other lesions. Characterization of visual association areas in the occipital and
temporal lobes with functional MRI (fMRI) and DTI was done. Upstream visual pathway insults may have downstream effects,
including cortical reorganization, which has implications on the associated clinical outcomes.
Discussion:
Advanced MRI techniques offer the ability to characterize pathology involving the visual pathway with a level a detail
that extends beyond the scope of both clinical examinations and conventional MR imaging. Familiarity with these sequences will
allow the radiologist to offer additional insights to referring clinicians, which is likely to positively impact patient management
