TLDR
It is concluded that MRN is a useful technique in evaluating patients with brachial plexus lesions, particularly in cases of brachIAL plexitis, where conventional magnetic resonance imaging is generally normal.Abstract:
Magnetic resonance neurography (MRN) is a relatively new imaging technique that is highly sensitive in detecting lesions in the peripheral nerves. We studied six cases of brachial plexopathies in which MRN played a pivotal role in making the correct diagnoses. All patients had clinical, nerve conduction, and electromyographic findings consistent with brachial plexus lesions. Four patients had brachial plexitis and two had multifocal demyelinating neuropathy presenting as brachial plexopathies. MRN in all patients showed edema, thickening, and T2 hyperintensities localized to the brachial plexus region. We conclude that MRN is a useful technique in evaluating patients with brachial plexus lesions, particularly in cases of brachial plexitis, where conventional magnetic resonance imaging is generally normal.read more

High-resolution and functional magnetic resonance imaging of the brachial plexus using an isotropic 3D T2 STIR (Short Term Inversion Recovery) SPACE sequence and diffusion tensor imaging
TL;DR: This technical note demonstrates the relevance of the isotropic 3D T2 turbo-spin-echo (TSE) sequence with short-term inversion recovery (STIR) and variable flip angle RF excitations for high-resolution brachial plexus imaging.

Perinatal brachial plexus palsy.
TL;DR: It is not possible to predict which infants are at risk for perinatal brachial plexus palsy, and therefore amenable to preventive measures, and there was no conclusive evidence that primary surgical exploration of the brachials supercedes conservative management for improved outcome.

TL;DR: Body weight for nerve CSA and BMI for PSD were identified as particularly important determinants, and may assist investigations into the potential of MRN biomarkers in further disease-specific studies.

Nerve injury associated with anesthesia.
TL;DR: It is concluded that nerve damage is a significant source of anesthesia-related claims but that the exact mechanism of nerve injury is often unclear and in particular, ulnar nerve injuries seemed to occur without identifiable mechanism.

TL;DR: The first "image neurogram" is presented and a method for producing such images by use of commercial magnetic resonance imaging systems is reported, which depicts a human nerve in situ in relation with a nerve graft.

TL;DR: Evidence from diverse sources now points to important somatotopic clustering of nerve fibers within most of the length of the nerve, which can produce restricted clinical deficits that defy the classic rules of localization.

Magnetic Resonance Neurography
TL;DR: This verifies the feasibility of generating three‐dimensional “neurographic” images, analogous to angiograms, but which demonstrate the peripheral nerve tracts in apparent isolation.
