Diffusion-weighted imaging (DWI) of the orbit is an
emerging MRI application to provide guidance during
diagnostic assessment and treatment of ophthalmological
diseases. The standard approach for DWI is EPI. EPI is
prone to severe geometric distortions, especially at
high and ultrahigh magnetic fields. Realizing these
constraints and the potential of ocular DWI, this work
uses diffusion sensitized multi-shot RARE for ophthalmic
MRI. This technique affords distortion free diffusion
weighted images of the orbit, which is demonstrated in
in-vivo images in healthy volunteers.
