Scanning pattern of diffusion tensor tractography and an analysis of the morphology and function of spinal nerve roots

This study uses a novel approach to diagnose radiculopathy, a condition often caused by intervertebral disk issues, by employing diffusion tensor magnetic resonance imaging (DT-MRI) to visualize and assess nerve root health. The study introduces a scoring system to quantitatively evaluate the morphology of nerve roots, providing an objective measure of nerve root function and alterations due to intervertebral disc degeneration. The research indicates that DT-MRI can be used to quantitatively assess nerve root function by examining the area and morphology of nerve root fiber bundles, potentially offering a more precise method for diagnosing and understanding radiculopathy.

• 1
  Fiber bundles in affected nerve roots tend to gather together and are often interrupted compared to unaffected nerve roots.
• 2
  The cross-sectional area of nerve root fibers is significantly reduced on the affected side in patients with radiculopathy.
• 3
  Morphological scoring revealed significant differences between affected and unaffected nerve root fibers, with affected fibers showing lower integrity and fewer branches.
