High resolution diffusion tensor MR imaging of the optic nerve is challenging due to the low SNR and distortions. We have obtained high resolution DTI based data and associated maps of fractional anisotropy (FA) and trace ADC of the optic nerve in a human subject at voxel sizes of 1mm x 1mm x 3mm. High resolution DTI of the optic nerve may be useful in the imaging evaluation of optical neuropathies.
