Abstract EN
The aim of this study was to characterize in vivo measurements of diffusion along the length of the entire healthy spinal cord and to compare DTI indices, including fractional anisotropy (FA) and mean diffusivity (MD), between cord regions.
The objective is to determine whether or not there are significant differences in DTI indices along the cord that must be considered for future applications of characterizing the effects of injury or disease.
A cardiac gated, single-shot EPI sequence was used to acquire diffusion-weighted images of the cervical, thoracic, and lumbar regions of the spinal cord in nine neurologically intact subjects (19 to 22 years).
For each cord section, FA versus MD values were plotted, and a k-means clustering method was applied to partition the data according to tissue properties.
FA and MD values from both white matter (average FA=0.69, average MD=0.93 × 10−3 mm2/s) and grey matter (average FA=0.44, average MD=1.8 × 10−3 mm2/s) were relatively consistent along the length of the cord.
