Objective to investigate the magnetic resonance diffusion tensor imaging in the diagnosis of mild myelopathic type. Methods in our hospital in 2012.6-2014.6 were 62 cases of mild spondylotic myelopathy (according to the cervical spinal mri scan results are divided into group A and group B, group A 32 cases, normal cervical spinal signal, compression of cervical spinal 60 segment; group B, 30 cases (group C)normal cervical spinal signal, compression of dural sac 63 section), and 30 healthy subjects were selected 90 cervical spinal segment mri examination, evaluation of each value fractional anisotropy (FA) and apparent diffusion coefficient (ADC).Evaluation parallel to the length to diameter of the cervical spine, before and after about diameter, the diameter of the eigenvalue E1, E2 and E3, calculate the average dispersion coefficient value, average transverse dispersion coefficient E⊥ an MD, MD=(E1+E2+E3)/3; E⊥=coming (E2 and E3)/2. Results healthy controls different spinal cord segment between the FA and ADC values differences had no statistical significance (P>0.05); Spinal cord segmental average ADC values of group A is significantly higher than in group C, statistically significant difference (P<0.05); Group A spinal cord segmental FA average significantly lower than that of group C, statistically significant difference (P<0.05); Group B of the spinal cord segmental average ADC values significantly higher than that of group C, statistically significant difference (P<0.05); Group B of the spinal cord segmental FA average significantly lower than that of group C, statistically significant difference (P<0.05). Conclusion mild magnetic resonance tensor imaging myelopathic type cervical vertebra disease, can accurately quantify the cervical spinal microstructure changes of the disease, early mild myelopathic type cervical vertebra disease diagnosis of early diagnosis findings have important clinical significance.
