Insights

Diffusion-weighted magnetic resonance imaging (DW-MRI) shows promise for spinal cord conditions. A new technique overcomes technical challenges, enabling high-resolution imaging for better diagnosis of intramedullary lesions.

Area of Science:

  • Medical Imaging
  • Neurology
  • Radiology

Background:

  • Diffusion-weighted magnetic resonance imaging (DW-MRI) can enhance diagnostic accuracy for spinal cord pathologies.
  • Technical challenges have limited the clinical application of DW-MRI for the spinal cord.

Purpose of the Study:

  • To evaluate a novel phase-navigated spin-echo diffusion-weighted interleaved echo-planar imaging sequence for spinal cord MRI.
  • To assess the feasibility and diagnostic potential of high-resolution DW-MRI of the spinal cord.

Main Methods:

  • A new DW-MRI sequence was tested in seven healthy volunteers and six patients with intramedullary lesions.
  • High spatial resolution imaging of the spinal cord was performed.

Main Results:

  • The novel sequence was successfully implemented for spinal cord DW-MRI.
  • Distinct patterns of diffusion abnormalities were observed in patients with intramedullary lesions.

Conclusions:

  • The developed DW-MRI technique is a viable method for high-resolution spinal cord imaging.
  • Observed diffusion abnormalities suggest DW-MRI has significant diagnostic potential for spinal cord diseases.
