脊髓亚急性联合变性的MRI特点研究

MRI Features of Subacute Combined Degeneration of Spinal Cord

目的分析脊髓亚急性联合变性的MRI特点。方法回顾性分析2016年1月—2016年12月在本院接受诊治的31例脊髓亚急性联合病变患者资料,为所有患者实施脊柱MRI检查,其中3例实施增强检查,基于检查结果分析影像学特点。结果31例接受MRI检查的脊髓亚急性联合病变患者中,30例出现髓内异常信号,阳性率为96.77%。24例脊髓后索及侧索受累,双侧对称;6例患者后索单独受累。患者病变表现为带状或者斑片状等T_1长T_2信号,STIR为高信号。3例实施增强扫描无强化。结论脊髓亚急性联合病变患者实施MRI检查,能够清晰观察到患者的病变情况与病灶位置,对脊髓亚急性联合患者的全面诊断与进一步治疗奠定良好的基础,临床检查应用价值突出。

Objective to analyze the MRI features of subacute combined degeneration of the spinal cord. Methods a retrospective analysis from January 2016 to December 2016 in our hospital 31 cases of spinal cord in the diagnosis and treatment of subacute combined diseases,for the implementation of spinal MRI in all patients,including 3 cases of the implementation of enhanced examination,examination results based on the analysis of imaging characteristics. Results in 31 patients with subacute combined spinal cord lesions in MRI,there were 30 cases of intramedullary abnormal signal,the positive rate was 96.77%. 24 cases of spinal cord posterior and lateral cord involvement,bilateral symmetry;in the 6 cases of posterior funiculus alone. The lesions of patients showed T1 long T2 signal,such as band or patchy,STIR was high signal. 3 cases of enhanced scan without enhancement. Conclusion MRI examination in patients with subacute combined lesions can be clearly observed in patients with lesions of the location of the lesion,lay a good foundation for further treatment and comprehensive diagnosis of subacute combined with the clinical application value of the examination of outstanding.
