Summary
Diffusion-weighted magnetic resonance (MR) neurography offers a clear overview of the brachial plexus. This technique effectively visualizes nerve pathways and disease locations in patients.
Area of Science:
- Radiology
- Medical Imaging
- Neuroimaging
Background:
- The brachial plexus is crucial for upper limb function.
- Imaging the brachial plexus can be challenging due to its complex anatomy.
Purpose of the Study:
- To introduce and evaluate diffusion-weighted (DW) magnetic resonance (MR) neurography for brachial plexus imaging.
- To assess the technique's ability to visualize the entire brachial plexus and identify pathologies.
Main Methods:
- Diffusion-weighted MR neurography was performed.
- Images were processed using a maximum intensity projection (MIP) technique.
- The technique was evaluated in five healthy volunteers and five patients.
Main Results:
- DW MR neurography successfully visualized the entire brachial plexus trajectory in healthy volunteers.
- The technique clearly identified disease locations in all patients.
- Excellent conspicuity of nerves and surrounding structures was achieved.
Conclusions:
- DW MR neurography is a valuable tool for brachial plexus imaging.
- The technique provides comprehensive overview images with high detail.
- It aids in diagnosing and understanding brachial plexus pathologies.
