Comparisons of DTI indicators in the affected areas of the three groups. The FA values of tumor lesions were significantly lower than those of cervical spondylosis and myelitis lesions. Furthermore, the mean diffusivity (MD) and radial diffusivity (RD) values of the tumor patients were significantly higher than the other two groups. Axial diffusivity (AD) showed no significant difference. * p < 0.05, ** p < 0.01, *** p < 0.001, **** p < 0.0001.
