摘　　要：目的:分析磁共振扩散张量成像(DTI)对脊髓型颈椎病(CSM)患者神经损伤的评估价值。方法:选择2012年1月-2015年3月我院收治的48例早期CSM患者作为实验组,选取同期48例健康者作为对照组,两组均接受MRI(核磁共振)和DTI检查,对两组FA(椎间盘层面颈髓各向异性)值、ADC(表现扩散系数)值进行比较,同时对DTT进行重建和分析。结果:实验组C3/4、C4/5、C5/6节段的颈髓FA值均比对照组降低,其ADC值均比对照组提高,两组之间有明显的统计学意义(P<0.05)。结论:相比于常规MRI,DTI技术通过水分子弥散的无创定量评估方式对颈髓和病理生理变化进行无损伤检查,以便早期诊断和鉴别颈髓病变情况。Objective: To evaluate the value of diffusion tensor imaging (DTI) in evaluating nerve injury in patients with cervical spondylotic myelopathy (CSM).Methods: 48 patients with early CSM in our hospital from January2012 to March2015 were selected as the experimental group and 48 healthy people as the control group.Both groups were examined by MRI (magnetic resonance imaging) and DTI.The values of FA (cervical spinal cord anisotropy) and ADC (manifestation diffusion coefficient) at intervertebral disc level were compared between the two groups.Reconstruction and analysis.Results: The FA values of C3/4,C4/5 and C5/6 segments in the experimental group were lower than those in the control group,and the ADC values were higher than those in the control group.There was significant statistical significance between the two groups (P < 0.05).Conclusion: Compared with conventional MRI,DTI provides noninvasive quantitative assessment of the cervical spinal cord and pathophysiological changes by means of water molecular diffusion for early diagnosis and differential diagnosis of cervical spinal cord lesions.
