[Abstract] Objective: To explore the sensibility of diffusion tensor imaging (DTI) in early detecting spinal cord injury in cervical spondylotic myelopathy.Materials and Methods: Cervical routine MRI and DTI were performed in 13 healthy volunteers and 13 patients with cervical spondylotic myelopathy. The radiological findings were analyzed, and the apparent diffusion coefficient (ADC) values and the fractional anisotropy (FA) values were calculated, and spinal cord fiber bundle was reconstructed.Results: Compared with control group, the mean ADC and FA values were higher (t=8.495, P<0.001) and the mean FA was lower (t=-14.328, P<0.001). The DTI color maps found abnormal signal at the compressed spinal cord. T2WI showed high signal at the compressed spinal cord in 4/13 (30.8%) patients. Fisher statistics proved that DTI was more sensitive than routine MRI (P=0.002).Conclusion: DTI can provide information about the pathology. It is more sensitive in early detecting spinal cord injury in cervical spondylotic myelopathy than routine MRI.
