[Abstract] Objective: To investigate the value of early diagnosis of the average diffusion coefficient (DCavg) and fractional anisotropy (FA) of the magnetic resonance diffusion tensor imaging (DTI) in hepatic cirrhosis patients with spinal cord lesions.Materials and Methods: According to the standard of Child-Pugh classification, select A, B and C-class (group) patients (15 cases respectively) and 15 cases of normal healthy volunteers as controls (Group D). All the subjects accept thoracolumbar spinal DTI scan, b=500 s/mm2, 25 different directions of diffusion gradient. Reconstruct the DCavg and FA pseudo-color pictures by the post-processing of raw data and measure its value. Analysis of variance is used for the comparison of A, B, C, D group, the Bonferroni is used for the multiple comparison between groups, t test is used for the comparison between the control group and the hepatic cirrhosis group.Results: The value of DCavg of thoracolumbar spinal in normal control group (15 cases) is (1.330±0.160) ×10-3 mm2/s, the value of FA is 0.320±0.150, the value of DCavg of thoracolumbar spinal in hepatic cirrhosis group (45 cases) is (1.415±0.250) × 10-3 mm2/s, the value of FA is 0.404±0.110, the difference of the value of DCavg and FA between the two groups are significant (t=4.896, P<0.05, t=16.456, P<0.05). The value of DCavg of thoracolumbar spinal cord in A, B, C group are respectively (1.342±0.100) ×10-3 mm2/s, (1.371±0.230) ×10-3 mm2/s, (1.492±0.290) ×10-3 mm2/s, the value of FA are respectively 0.353±0.110, 0.385±0.130, 0.446±0.090. The difference of the value of DCavg and FA among the groups is significant (P<0.05). The value of DCavg and FA in group C are higher than the Group A, B and D, the difference is significant (P<0.05). The difference of the value of DCavg and FA between Group A and D is no significant difference (P>0.05).Conclusions: Compared with the normal, the value of DTI DCavg and FA of thoracolumbar spinal cord values in patients with hepatic cirrhosis is higher, the DTI could provide more information for the early diagnosis and condition assessment in hepatic cirrhosis patients with spinal cord lesions.
