This is a prospective study on lumbar disc herniation patient and healthy control with diffusion tensor imaging (DTI) and tractography (DTT). We obtained a high success rate (>90%) of achieving the DTI with tractography of lumbar nerve roots was in this study, and revealed that DTI and DTT technique can both display intensity and morphology changes in the compressed areas of lumbar nerve roots. DTI with tractography provides an abundant diagnostic information with specificity on both qualitative- and quantitative-wise, which is great helpful to assess the disorders with lumbar nerve root compression.
