In this study, we aim to investigate if diffusion tensor imaging can clinically evaluate lumbosacral radiculopathy before and after percutaneous transforaminal endoscopic discectomy. By measuring 66 patients pre- and post-operatively, we found the FA values at the proximal sub-regions (subarticular zone) are more effective and had a significant correlation with clinical symptoms. Besides, both located in the proximal sub-regions, the abnormal parts of DTT visualized nerves coincided with the changes of the FA values in compressed nerves before and after surgery. Therefore, in lumbosacral radiculopathy, DTI is a potential tool for clinical evaluation before and after PETD surgery.
