Diffusion tensor imaging in spinal dysraphism. a Diffusion tractography of a foetus with spinal dysraphism, 26th week of gestation. The fibre tracts (colour representing spatial orientation) have been overlaid on a coronal plane, T2-weighted MR image. b Sagittal T2-weighted MRI of a newborn with spina bifida, corrected prenatally, showing signs of tethered cord. c Sagittal fractional anisotropy image of the same myelon cross-section, demonstrating increased anisotropy in the region of the tethering. d Diffusion tensor principal vector orientations in the same region. e Diffusion tractography of the myelon
