Abstract:
Due to its excellent sensitivity, MR imaging is invaluable for the evaluation of lesions of the cord and spine. Several studies dedicated to diffusion-weighted MR evaluation of the cord and spine have been published. While diffusion-weighted MR imaging of the brain is routinely performed, it is seldom performed when imaging the spine due to serious limitations. While anatomical limitations may not be changed, the voxel size, phase-encoding direction, mode of k-space filling, and acceleration factor are all parameters that can be optimized in order to routinely obtain diffusion-weighted imaging of the spine on 1.5T and 3T scanners.
Insights
Diffusion-weighted MRI (DW-MRI) is sensitive for spinal lesions but faces limitations. Optimizing imaging parameters can enable routine DW-MRI of the spine on 1.5T and 3T scanners.
Area of Science:
- Radiology
- Medical Imaging
- Neuroimaging
Context:
- Magnetic Resonance (MR) imaging offers high sensitivity for evaluating spinal cord and spine lesions.
- Diffusion-weighted imaging (DWI) is standard for brain evaluation but rarely used for the spine due to significant technical challenges.
Purpose:
- To identify and address the limitations hindering routine diffusion-weighted MR imaging of the spine.
- To propose optimization strategies for acquiring high-quality DWI of the spine.
Summary:
- While anatomical constraints are fixed, parameters such as voxel size, phase-encoding direction, k-space filling, and acceleration factor can be adjusted.
- These optimizations aim to overcome current limitations and facilitate the routine use of DWI for spinal imaging.
Impact:
- Enables routine diffusion-weighted MR imaging of the spine on 1.5T and 3T scanners.
- Improves diagnostic capabilities for spinal cord and spine pathologies.
- Enhances the clinical utility of advanced MRI techniques in neuroimaging.
