Degenerative cervical myelopathy (DCM) is a chronic disease of spinal cord. The sensitivity of conventional structural T1W and T2W MRI to the diagnosis of DCM is low. Diffusion tensor imaging (DTI) can provide quantitative assessments for pre- and post-surgery spinal cord functions. However, the prognostic value of DTI metrics at the level-of-most-compression (LMC) remains controversial. Additionally, it is difficult to differentiate the clinical utility of various tracts at LMC due to severe compressions and limited resolution. This retrospective cohort follow-up study aimed to investigate the correlation of DTI metrics with clinical assessment in different tracts at non-compressed C2 level.
