Abstract: This study investigated the efficacy of magnetic resonance imaging (MRI) in predicting the postoperative recovery of spinal cord function in patients with spinal cord injury without radiological abnormalities (CSCIWORA). 139 patients with CSCIWORA caused by sports falls were selected as the research subjects, and they were divided into good group (n=103) and non-good group (n=36) according to the recovery situation of spinal cord function after surgery. The general data and MRI test results of the two groups were compared, and the data Statistical analysis was performed. The results showed that the time from injury to surgery was longer in the non-good group than in the good group, and the ASIA classification of spinal cord injury was more severe than in the good group (P<0.05). The patients in non-good group with spinal cord injury MRI type edema + hemorrhage and anterior cervical MRI high signal were more than the good group, and the signal length of spinal cord injury was higher than in the good group, while the effective cervical canal rate was lower than in the good group (P<0.05). Time from injury to operation, American Spinal Injury Association (ASIA) classification of spinal cord injury, MRI type of spinal cord injury, cervical MRI prevertebral hyperintensity, signal length of spinal cord injury, and effective cervical spinal canal rate were all correlated with the improvement rate of the Japanese Orthopaedic Association (JOA) score (P<0.05). The AUC of spinal cord injury signal length was the largest among single MRI parameters, but it was still lower than the AUC of all MRI parameters combined (0.922). It can be seen that the type of spinal cord injury MRI, cervical MRI prevertebral high signal, spinal cord injury signal length and effective cervical canal rate are related to the recovery of spinal cord function in patients with CSCIWORA after surgery. MRI technique can reliably predict the regression of spinal cord function after surgery.
