Synopsis

There are still many unclear issues in the motions of the spinal cord. This study is the first report to use optical flow analysis for quantitative evaluation of spinal cord motions. In the study of healthy volunteers, we found large displacement of the upper thoracic spinal cord. The study of clinical cases revealed that the spinal cord displacement changed before and after surgery. Therefore, these results suggested that quantitative evaluation of spinal cord motions is feasible using optical flow analysis.
