Abstract: Objective To explore the application value of diffusion tensor imaging and diffusion tensor tractography in the benign lesion of spinal cord.Methods 30 cases with the benign lesions of spinal cord and 10 healthy volunteers underwent MRI and DTI scanning by 1.5T MR.Results Compared with normal control group,ADC values [(1.29±0.24)×10 -3 mm2/s]of extramedullary group-Ⅰwere increased slightly,and FA values (0.46±0.06)were decreased slightly(P <0.05).In extramedullary group-Ⅱ,ADC values [(2.03±0.19)×10-3 mm2/s]were significantly increased and FA values (0.37±0.03)decreased in the lesion level (P <0.05).The ADC values [(1.71±0.24)×10 -3 mm2/s]of intramedullary group was significantly elevated,and the FA values (0.30±0.06)was obviously reduced (P <0.05 ).The fiber tracts showed the abnormality of the white matter,including compression,sparseness, grow downwards,interruption and other changes.Conclusion The changes of the FA and ADC values,diffusion tensor imaging of the bundle can quantitatively evaluate the severity of spinal cord damage and stereo display fiber bundle damage.
