Recent studies suggest that DTI values in the human cervical spinal cord may be susceptible to motion related noise caused by the flow of the CSF. It has been established that the cervical spinal cord pulsates with the cardiac cycle displacing 0.6 mm on average following systole. In the current study, corruption due to motion is observed in ADC values of the cervical spinal cord compared to values collected in the lumbar cord where motion is negligible. DTI data has been binned at consistent phases of the cardiac cycle and consistent cord position therefore minimizing the effects due to motion.
