Apparent diffusion tensor (ADT) measurements on the spinal cord using a pulsed-field-gradient (PFG) multi-shot echo-planar imaging (EPI) sequence are presented. In a study of 10 healthy volunteers, the obtained rotationally invariant anisotropy information is compared to the results obtained by the
## Abstract In vivo longitudinal diffusion tensor imaging (DTI) of rodent spinal cord injury (SCI) was carried out over a period of eight weeks postβinjury. A balanced, rotationally invariant, alternating gradient polarity icosahedral diffusion encoding scheme was used for an unbiased estimation of
## Abstract Diffusion tensor imaging (DTI) has the potential to provide important information about the integrity of white matter tracts in injured spinal cord tissue. It is thought that DTIβbased transverse diffusivity (Ξ»~__t__~) reflects the state of myelin, whereas longitudinal diffusivity (Ξ»~__
