Magnetic Resonance Imaging

Magnetic Resonance Imaging

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...

Background:

Peripheral nerve assessment traditionally relies on clinical examination and electrodiagnostic studies.
Limitations in visualizing small nerve structures and subtle pathologies exist with conventional imaging.
Advancements in magnetic resonance neurography (MRN) offer improved diagnostic capabilities.

Purpose of the Study:

To review the technical considerations for acquiring high-resolution isotropic volumetric three-dimensional (3D) MRN images.
To summarize the clinical applications of 3D MRN in evaluating various peripheral nerve diseases.
To highlight the diagnostic value of 3D MRN in conditions affecting peripheral nerves.

Main Methods:

Review of current literature on 3D MRN techniques and clinical applications.
Focus on isotropic volumetric acquisition protocols for optimal multiplanar nerve depiction.
Synthesis of findings from studies assessing peripheral nerve pathologies using 3D MRN.

Main Results:

High-resolution isotropic volumetric 3D MRN enables detailed multiplanar visualization of peripheral nerves.
3D MRN provides crucial anatomical and functional tissue characterization for diagnosing nerve conditions.
Clinical applications demonstrated for entrapments, trauma, inflammatory neuropathies, and neoplasms.

Conclusions:

3D MRN is a powerful tool for peripheral nerve imaging, offering superior anatomical detail.
Technical optimization of 3D MRN acquisition is essential for maximizing diagnostic yield.
3D MRN significantly enhances the assessment and characterization of a wide spectrum of peripheral nerve diseases.
