DTI can detect changes in white matter bundles that were not found by conventional MRI between mild HIBD and control group, showing promises for its use in the early diagnosis of HIBD. The FA values can reflect the development of prognosis.  
Table 1 The comparison of nonparametric test of FA values in four groups
Fig.1 The multiple comparisons’results of four groups (†, p < 0.05; *, p < 0.001)The multiple comparisons between each HIBD subgroup (mild, moderate and severe group) and the control group were analyzed using Bonferroni method with significantly difference denoted by † p < 0.05, * p < 0.001.
