MRDTI
normative data from the optic nerves in 70 normal children was compared to
diffusion parameters in children with lesions both intrinsic and extrinsic to
the visual pathway. Significant
decrease in FA and increase in ADC was present in intrinsic lesions, while
extrinsic lesions where only mass effect on the nerves was present did not
affect diffusivity or anisotropy. This
may improve presurgical planning for visual pathway lesions.
