摘　　要：目的:探讨脊髓亚急性联合变性(Subacute Combined Degeneration,SCD)的MRI表现特点。方法:回顾性分析15例经临床确诊的亚急性联合变性患者,均行MR检查(矢状位T1WI、矢状位T2WI及轴位T2WI),其中4例于治疗后复查MRI。结果:所有患者颈髓和/或胸髓内均可见对称性等或稍长T1长T2信号,病变分别位于侧索(3例)、后索(7例)、侧索及后索(5例),脊髓无明显肿胀;4例治疗后复查病灶缩小或消失。结论:MRI对于脊髓亚急性联合变性的诊断和随访具有很好的适用性和有效性。To discuss the MRI characteristics of subacute combined degeneration（ SCD） of the spinal cord. Methods： Fifteen patients diagnosed with SCD were retrospectively analyzed. All patients underwent MR scan（ sagittal T1 WI,sagittal T2 WI and axial T2WI）,and four of them were re-inspected with MR scan after treatment. Results： All patients showed symmetrically equal or slightly long T1 and long T2 signal in their cervical cord and/or thoracic cord; corresponding lesions located in lateral column（ 3 cases）,posterior column（ 7 cases） and both（ 5 cases） respectively. No obvious swelling in spinal cord was observed. Four lesions diminished or disappeared in MR re-inspection after treatment. Conclusion： MRI is applicable and effective for the diagnosis and follow-up of SCD.
