Predictive value of flexion and extension diffusion tensor imaging in the early stage of cervical myelopathy.

Purpose: Diffusion tensor imaging (DTI) in flexion (F) and extension (E) may serve as a sensitive diagnostic tool in early symptoms of myelopathy. The aim of this study was to compare values of water diffusion parameters on dynamic cervical DTI in early stage of myelopathy.

Methods: Study enrolled 10 patients with an early stage of cervical myelopathy, in grade I/II of Nurick classification.
