Perfusion of Spinal Cord in postoperative patient with Cervical Spondylotic Myelopathy using MR DSC technique

Cervical Spondylotic Myelopathy (CSM) is a major cause of spinal cord dysfunction. However, the relationship between the degree of stenosis, tissue degeneration and sensorimotor dysfunction have not been well understood.In this study, 3 healthy volunteers and 17 CSM patients with different postoperative recovery degree were involved. We investigate the perfusion of spinal cord using MR DSC technique. The results showed a significant correlation between CBV and the postoperative severity of symptom (Japanese Orthopaedic Association score), which indicate that MR DSC perfusion of spinal cord could be an imaging biomarker to evaluate and understand CSM.
