Objective To explore the routine MRI findings of cervical spinal cord injury and clinical effect of DTI technique. Methods 46 patients with suspected cervical spinal cord injury cured in our hospital from December 2014 to December 2016 were selected, and 40 cases for physical examination in our hospital were selected as control group. The 46 patients with suspected cervical spinal cord injury and the 40 cases of healthy person performed routine MRI and DTI technical examinations. The diagnostic accuracy, sensitivity and specificity of MRI and DTI techniques, routine MRI findings and DTI techniques of the two groups were explored and compared. Results The accurate rate of routine MRI and DTI diagnosis of cervical spinal cord injury was 97.56%, the results of the test and the final diagnosis of the clinical comparison, there was no significant difference between the two( P 0.05). The sensitivity of conventional MRI scan and DTI technique in diagnosing cervical spinal cord injury was 97.50%(39/40), and the specificity was 66.67%(4/6). The ADC value of 40 patients with cervical spinal cord injury was significantly higher than that of the control group, but the FA value was significantly lower than that of the control group(P 0.05). And the ADC and FA values of acute cervical compression group, the chronic cervical spinal cord compression group, the cervical spinal cord chronic compression group with acute compression group were significantly different(P 0.05). Conclusion It is feasible to diagnose patients with cervical spinal cord injury by conventional MRI and DTI techniques. It can provide the basis for clinicians to diagnose cervical spinal cord injury and its typing.
