DIFFUSION TENSOR IMAGING OF CERVICAL SPINAL CORD A 3T : NORMAL VALUES OF RADIAL, AXIAL, MEAN DIFFUSIVITY AND FRACTIONAL ANISOTROPY IN ANTERIOR HORN, DORSAL FUNICULUS AND PYRAMIDAL TRACT AT EACH CERVICAL LEVEL

From a commercially available axial SE-EPI DTI sequence, after empirical optimizations in order to limit distortion in an acceptable scan time, our aim was to determine the normal values of DTI parameters (mean diffusivity, axial diffusivity, radial diffusivity and fractional anisotropy) in key locations of cervical spine (cortico spinal tract, posterior column and anterior horn, full spine section) at each cervical level from C1 to C7.
