摘要:
目的：分析3.0T磁共振（MR）扩散张量成像（DTI）序列对脊髓型颈椎病（CSM）的诊断价值。方法：选择福建中医药大学附属康复医院收治的30例CSM患者纳入观察组，另选择同期体检人群中年龄匹配的30例健康志愿者为对照组，均运用常规MRI序列及DTI技术进行扫描，运用DTI技术测量FA及ADC值，进行图像后处理及数据分析，观察组患者根据MR平扫结果分为A组（n=10，单纯硬膜囊受压）、B组（n=14，颈髓受压，信号正常）和C组（n=6，颈髓受压，T2WI高信号），分析各组FA及DA值差异，评价DTI诊断脊髓型颈椎病的诊断价值。结果：对照组脊髓C2-3、C3-4、C4-5、C5-6、C6-7节段的ADC值与FA比较差异无统计学意义（P>0.05）；对照组与A、B、C组的ADC值、FA值存在显著性差异（P<0.05），B组、C组的ADC值显著高于对照组（P<0.05），FA值显著低于对照组（P<0.05），A组ADC值、FA值与对照组比较差异无统计学意义（P>0.05）；从A组到C组，ADC值呈升高趋势，FA值呈降低趋势，差异显著（P<0.05）；MR T2WI、DTI序列扫描FA值、MR DTI序列扫描ADC值诊断扫描诊断CSM的敏感度与特异度为20.00%（6/30）与80.00%（24/30），80.00%（24/30）与20.00%（6/30），66.67%（20/30）与30.00%（9/30）。结论：DTI较常规MRI能更早期而准确地诊断CSM，是一种显示CSM病变和观察病变修复过程的有效手段。
Abstract:
To analyze the diagnostic value of 3.0T diffusion tensor magnetic resonance imaging (MR DTI) sequence in cervical spondylotic myelopathy (CSM). Methods Thirty patients with CSM admitted to the Affiliated Rehabilitation Hospital of Fujian University of Traditional Chinese Medicine were enrolled in observation group, while 30 age-matched healthy volunteers among physical examination population were selected as control group. The routine MRI sequence and DTI technology were used for scanning, and DTI technique for measuring fractional anisotropy (FA) values and apparent diffusion coefficient (ADC) values. Image post-processing and data analysis were also performed. The patients in observation group were divided into group A (n=10, simple dural sac compression), B (n=14, cervical spinal cord compression, normal signals) and C (n=6, cervical spinal cord compression, T2WI high signals) according to the results of MR plain scan. The differences of FA values and ADC values were analyzed in each group, and the diagnostic value of DTI in CSM was evaluated. Results No statistical difference was found in the FA values and ADC values of spinal cord C2-3, C3-4, C4-5, C5-6 and C6-7 segments in control group (P>0.05). There were significant differences in FA values and ADC values among control group and groups A, B and C (P<0.05). Compared with control group, groups B and C had significantly higher ADC values (P<0.05), but obviously lower FA values (P<0.05). The FA values and ADC values in group A were similar to those in control group, without statistical significance (P>0.05). From group A to C, ADC values showed an increasing trend; while FA values showed a decreasing trend, with significant differences (P<0.05). The sensitivity and specificity of FA values obtained by MR T2WI and DTI sequence and ADC value obtained by MR DTI sequence in the diagnosis of CSM were 20.00% (6/30) and 80.00% (24/30), 80.00% (24/30) and 20.00% (6/30), and 66.67% (20/30) and 30.00% (9/30). Conclusion DTI which is an early and accurate diagnosis of CSM cervical com pared with routine MRI is an effective means to show CSM lesions and observe the pathological repair process.
