Tractography for spinal dysraphism

Tractography for spinal dysraphism exemplified in a 53-year-old women with diastematomyelia. Panel A shows two hemicords on an axial T2-weighted image at L3 level, with the larger cord on left (arrow). Panel B shows tractography of the two hemicords. The axial image represents color-coded FA map. Larger tract (light blue) is composed of greater number of individual fiber tracts and corresponds to larger (left) hemicord.
