[Abstract] Objective: To investigate the value of MRI in the diagnosis of spinal cord injury and the evaluation of neurological function in patients with cervical spinal cord injury without fracture and dislocation.Materials and Methods: Retrospective analysis was performed on 39 patients (experimental group) and 39 healthy subjects (control group) without fracture and dislocation cervical spinal cord injury who were treated in Yantai Mountain Hospital from January 2013 to July 2018. The sagittal diameter and area of cervical spinal cord, dural sac and spinal canal in the C2-C7 segment of the control group and the experimental group were measured respectively, and the sagittal diameter ratio and area ratio among the three segments were calculated, and the differences in the parameters between the two groups were analyzed. The extent of cervical spinal cord injury in SCIWFAD patients was recorded and the extent of injury was measured. The extent of cervical spinal cord injury and the correlation between cervical spinal cord injury and ASIA grade were analyzed according to ASIA criteria.Results: The area of cervical spinal cord was better than the sagittal diameter in SCIWFAD patients. D cervical spinal cord/dural sac and D cervical spinal cord/spinal canal, S cervical spinal cord/dural sac and S cervical spinal cord/spinal canal can better reflect the spinal cord compression and spinal cord volume reserve when spinal canal volume changes in patients with SCIWFAD. The ASIA neurological functional grading was closely related to the extent of injury (r= -0.519, P=0.001), but had no definite correlation with the extent of injury (r=-0.013, P=0.892).Conclusions: MRI can accurately display the injury range and signal change of SCIWFAD, and both the dural sac and spinal canal sagittal diameter and area can accurately evaluate the spinal canal reserve space of the spinal cord. The extent of spinal cord injury can accurately reflect the severity of spinal cord functional injury.
