采用磁共振成像技术对55例颈椎压迫性脊髓病患者的脊髓可塑性进行了评估，通过测量手术前后最大压迫部位的脊髓横截面积，并与传统的计算机断层脊髓造影进行比较。脊髓造影与磁共振成像的术前测量值有高度相关性（r = 0.901，P < 0.01）。术前横截面积与术前日本骨科协会评分有良好的相关性（r = 0.466，P < 0.01）。在大多数脊髓面积小于0.45 cm 2的患者中，尽管减压手术后获得了相当大的椎管形态恢复，但临床结果较差，反映了脊髓中出现的不可逆病理学。
Spinal cord plasticity in 55 patients with cervical compression myelopathy was assessed with magnetic resonance imaging, by which the transverse area of the spinal cord was measured at the site of maximum compression before and after surgery and compared with the conventional modalities of computed tomographic myelography. A high correlation (r = 0.901, P < 0.01) was observed between the preoperative measurements of magnetic resonance imaging and computed tomographic myelography. The preoperative transverse area was in good correlation with the preoperative Japanese Orthopaedic Association score (r = 0.466, P < 0.01). In most patients with a spinal cord area of less than 0.45 cm2, the clinical results were poor despite considerable morphologic restoration of the spinal canal obtained after decompression surgery, reflecting an irreversible pathology developed in the spinal cord.
