The cerebrospinal fluid (CSF) flow in the cervical
spine was compared between healthy controls and persons with spinal cord injury
(SCI) using phase contrast MRI. The subarachnoid
cross-section of SCI participants was smaller than that of healthy controls.
The flow velocities in both diastolic and systolic cardiac phases were faster
in SCI participants than that of healthy controls. Considering a slower heart
rate and a reduced ejection fraction and stroke volume of the heart in SCI participants,
the reduced subarachnoid area may be a main contributing factor to the
increased velocity of CSF flow in SCI participants.
