STUDY DESIGN: Prospective case-control study. OBJECTIVES: We investigated the use of the magnetization transfer saturation (MTsat) technique to assess the structural integrity of the spinal cord tracts in individuals with clinically significant degenerative cervical myelopathy (DCM) and associated disability. SETTING: Novosibirsk Neurosurgery Centre, Russia. METHODS: A total of 53 individuals diagnosed with DCM and 41 patients with cervical radiculopathy underwent high-resolution MRI of the cervical spinal cord via the magnetization transfer technique. The MRI data were processed using the Spinal Cord Toolbox (v5.5), with MTsat values determined for each spinal tract and compared between the two groups. Furthermore, associations between MTsat values and the clinical disability rates of patients were investigated. RESULTS: A significant decrease in the MTsat of the ventral spinocerebellar tract was observed in the DCM group compared to the control group (adjusted p < 0.001). There was a trend towards lower MTsat values in the rubrospinal tract in the DCM group (adjusted p = 0.08). Additionally, a decrease in MTsat values in the lateral funiculi of the spinal cord was found in patients with DCM (adjusted p < 0.01). Furthermore, a trend toward a positive correlation was observed between the JOA score and the MTsat values within the ventral spinocerebellar tract (R = 0.33, adjusted p = 0.051). CONCLUSIONS: The findings of our study indicate that demyelination in patients with DCM affects mainly the ventral spinocerebellar and rubrospinal tracts, and the extent of changes in the ventral spinocerebellar tract is related to the severity of the condition.
研究设计:前瞻性病例对照研究。 目的:我们研究了磁化传递饱和(MTsat)技术在评估患有临床显著退行性颈椎脊髓病(DCM)和相关残疾的个体脊髓束结构完整性中的应用。 地点:俄罗斯新西伯利亚神经外科中心。 方法:共有 53 名诊断为 DCM 的患者和 41 名颈椎神经根病患者接受了颈椎脊髓高分辨率 MRI 通过磁化传递技术。使用 Spinal Cord Toolbox(v5.5)对 MRI 数据进行处理,确定每个脊髓束的 MTsat 值,并在两组之间进行比较。此外,还研究了 MTsat 值与患者临床残疾率之间的相关性。 结果:与对照组相比,DCM 组的腹侧脊髓小脑束的 MTsat 值明显降低(调整后 p<0.001)。DCM 组红核脊髓束的 MTsat 值呈下降趋势(调整后 p=0.08)。此外,DCM 患者脊髓外侧束的 MTsat 值也降低(调整后 p<0.01)。此外,还发现 JOA 评分与腹侧脊髓小脑束内的 MTsat 值之间存在正相关趋势(R=0.33,调整后 p=0.051)。 结论:我们的研究结果表明,DCM 患者的脱髓鞘主要影响腹侧脊髓小脑束和红核脊髓束,腹侧脊髓小脑束变化的程度与病情的严重程度有关。
