Summary
Magnetic resonance (MR) neurography offers advanced noninvasive imaging for brachial plexus abnormalities. This technique is crucial for diagnosing injuries, tumors, and inflammation, especially in pediatric cases.
Area of Science:
- Radiology
- Neurology
- Medical Imaging
Background:
- Brachial plexus abnormalities require accurate noninvasive diagnostic methods.
- Magnetic resonance (MR) neurography is an evolving imaging modality with significant potential.
Purpose of the Study:
- To review the applications and techniques of MR neurography for evaluating the brachial plexus.
- To highlight the clinical utility of MR neurography in various brachial plexus pathologies.
Main Methods:
- Overview of structural MR neurography techniques, including STIR sequences in 2D and 3D.
- Description of microstructural MR neurography, focusing on diffusion tensor imaging and tractography.
- Emphasis on appropriate technique selection and understanding of pathologies.
Main Results:
- MR neurography is clinically useful for traumatic injuries, tumors, and post-radiogenic inflammation of the brachial plexus.
- It is particularly beneficial for pediatric patients with obstetric brachial plexus trauma.
- Both structural and microstructural MR neurography techniques provide valuable diagnostic information.
Conclusions:
- MR neurography is a powerful tool for noninvasive evaluation of the brachial plexus.
- Successful assessment relies on appropriate technique implementation and knowledge of brachial plexus pathologies.
- This imaging modality aids in diagnosing a range of conditions affecting the brachial plexus.
