【摘要】：目的探讨3.0 T MR扩散张量成像(DTI)技术对慢性压迫性损伤的早期诊断价值。方法 40例慢性压迫性颈髓损伤患者行常规MRI及DTI检查。实验组分为A1、A2两组,A1组常规MR-T2WI显示颈髓内无异常信号者20例,A2组常规MR-T2WI显示受压部位颈髓出现高信号者20例。选取A1组中非狭窄节段(颈2平面)脊髓作为对照组。分别测量A1、A2及对照组FA值与ADC值,行统计学分析。结果与正常对照组相比,A1组FA值明显降低,ADC值有所升高,结果差异均有显著统计学意义(P0.05)。与A1组患者相比,A2组FA值进一步明显降低,ADC值显著升高,结果差异均有显著统计学意义(P0.05)。结论 DTI能够早期发现常规MRI检查不能显示的颈髓异常。
[Abstract]:Objective to evaluate the value of 3. 0 T Mr diffusion Zhang Liang DTI technique in the early diagnosis of chronic compression injury.Methods 40 patients with chronic compressive cervical spinal cord injury were examined by routine MRI and DTI.The experimental group was divided into two groups: group A _ 1 A _ 2 and A _ 1 group A _ 1 group: 20 cases had no abnormal signal in cervical spinal cord by conventional MR-T2WI and 20 cases in group A _ 2 showed high signal intensity in cervical spinal cord under compression by routine MR-T2WI.The non-stenosis spinal cord (cervical 2 plane) in group A1 was selected as control group.FA value and ADC value of A _ 1 A _ 2 and control group were measured and analyzed statistically.Results compared with the normal control group, the FA value of A 1 group decreased significantly and the ADC value increased, and the difference was statistically significant (P 0.05).Compared with A1 group, the FA value of A _ 2 group further decreased significantly, and the ADC value increased significantly, and the difference was statistically significant (P 0.05).Conclusion DTI can detect early cervical spinal cord abnormalities which can not be detected by conventional MRI.
