Objective: To investigate the correlations between preoperative diffusion tensor imaging (DTI), a Magnetic Resonance Imaging (MRI)-based technique and surgical outcome in patients with cervical spondylotic myelopathy (CSM). Methods: A retrospective study of 95 patients with CSM who received diagnosis and surgical treatment in our hospital was carried out. According to the recovery rate of the Japanese Orthopaedic Association (JOA) scale at the 1-year postoperative follow-up, the patients were divided into a good recovery group (JOA recovery rate ≥60%, n = 47) and a poor recovery group (JOA recovery rate 0.05). Pearson correlation analysis showed that the preoperative FA value was positively correlated with the JOA recovery rate (P0.05). The CR, TA, MSCC and MCC values measured before surgery in the good recovery group were significantly lower than those in the poor recovery group (all P0.05). Conclusion: DTI can evaluate the severity of the patient’s condition before surgery by analyzing the subtle structural changes in patients with CSM. At the same time, the preoperative FA, VD, CR, MSCC, and MCC values are all associated with the surgery efficacy, which paves the way for the next step of clinical treatment. |
