文摘

Background In cervical myelopathy, significant findings are seen in flexion–extension MRI due to the increased likelihood of cord compression during neck extension. In addition, a high intramedullary signal on T2-weighted MR images has been reported to be a prognostic factor in this condition. However, the relationship between Japanese Orthopaedic Association (JOA) scores and the signal intensity in preoperative cervical flexion–extension T2-weighted images has not been evaluated. The purpose of this study was to evaluate whether preoperative flexion–extension MRI may be used to predict surgical outcomes in patients with cervical myelopathy.
