The aim of this study is mainly to explore the pre-diagnosis value of DTI technology applied to lumbosacral radiculopathy (LSR). By measuring 80 patients with unilateral disc related lumbosacral nerve root compression, we found that DTI technology combined with tractography not only could identify the type of disc herniation, assess the degree of nerve root damage, but also confirm the responsible nerve root. Therefore, we can demonstrate that DTI combined with tractography can improve the diagnosis rate of LSR and reduce iatrogenic injury.
