Diffusion-weighted echo planar imaging of the normal human cervical spinal cord

J Comput Assist Tomogr. May-Jun 2000;24(3):482-5. doi: 10.1097/00004728-200005000-00023.

Abstract

We obtained diffusion-weighted echo planar images of the human cervical cord in vivo and correlated them with histopathologic findings. Images were obtained in 17 healthy volunteers using a 1.5 T clinical MR unit. When motion-probing gradients were added perpendicular to the long axis of the cord, the white matter was hyperintense because of anisotropic diffusion. However, the gracile fasciculus was hypointense probably due to the small diameter of neural fibers and the large extracellular space.
