Peripheral Nervous System Reconstruction Reroutes Cortical Motor Output-Brain Reorganization Uncovered by Effective Connectivity.

Front Neurol 2018 18;9:1116. Epub 2018 Dec 18.

Study Group Clinical fMRI, Department of Neurology, Medical University of Vienna, Vienna, Austria.

Cortical reorganization in response to peripheral nervous system damage is only poorly understood. In patients with complete brachial plexus avulsion and subsequent reconnection of the end of the musculocutaneous nerve to the side of a phrenic nerve, reorganization leads to a doubled arm representation in the primary motor cortex. Despite, homuncular organization being one of the most fundamental principles of the human brain, movements of the affected arm now activate 2 loci: the completely denervated arm representation and the diaphragm representation.

Ultrasound of the Normal Brachial Plexus.

J Belg Soc Radiol 2017 Dec 16;101(Suppl 2):20. Epub 2017 Dec 16.

Reine Fabiola Children's University Hospital, Université Libre de Bruxelles, BE.

Ultrasound (US) allows a reliable examination of the brachial plexus except for the spinal nerve roots, located deep in the neuro-foramina, beyond the shadowing of the transverse processes of the vertebral bodies. All the other fascicles of the brachial plexus can be mapped by US from the roots of the spinal cervical nerves, from C5 to T1 to the branches at level of the axillary region. US can be considered as an alternative to Magnetic Resonance Imaging (MRI) when MRI is contraindicated, not readily available or in case of claustrophobia. Read More

Improved functional outcome in NTOS patients following resection of the subclavius muscle with radiological signs of nerve impingement: indication of participation of the subclavius in brachial plexus compression.

J Neurosurg 2018 Nov 1:1-11. Epub 2018 Nov 1.

OBJECTIVEBoth clinical and radiological reports have suggested that the subclavius, a muscle in the costoclavicular space of the thoracic outlet, participates in neurogenic thoracic outlet syndrome (NTOS) in some instances, especially during movements narrowing the costoclavicular space. Magnetic resonance imaging can identify subclavius muscles with signs of nerve impingement, yet the impact of the subclavius in such situations remains unclear. Therefore, the authors investigated whether dividing or sparing the subclavius characterized by nerve impingement on MRI would affect surgical outcomes. Read More

Department of Radiology, University of Texas Southwestern Medical Center, Dallas, Texas, USA.

Background: The 3D short tau inversion recovery (STIR) sequence is routinely used in clinical MRI to achieve robust fat suppression. However, the performance of the commonly used adiabatic inversion pulse, hyperbolic secant (HS), is compromised in challenging areas with increased B and B inhomogeneities, such as brachial plexus at 3T.

Purpose: To demonstrate the frequency offset corrected inversion (FOCI) pulse as an efficient fat suppression STIR pulse with increased robustness to B and B inhomogeneities at 3T, compared to the HS pulse. Read More

Improved Brachial Plexus Visualization Using an Adiabatic iMSDE-Prepared STIR 3D TSE.

Clin Neuroradiol 2018 Jul 23. Epub 2018 Jul 23.

Department of Diagnostic and Interventional Radiology, Klinikum rechts der Isar, Technical University of Munich, Ismaninger Str. 22, 81675, Munich, Germany.

Purpose: The close proximity of blood vessels to the brachial plexus nerves can confound nerve visualization in conventional fat-suppressed 3D T2-weighted sequences. Vessel suppression can be accomplished by means of motion-sensitizing preparation. The aim of this study was to qualitatively and semi-quantitatively evaluate short tau inversion recovery (STIR) 3D turbo spin echo (TSE) in conjunction with an adiabatic T2 preparation incorporating motion sensitization for magnetic resonance neurography (MRN) of the brachial plexus in a clinical routine setting.

Small-worldness of brain networks after brachial plexus injury: A resting-state functional magnetic resonance imaging study.

Neural Regen Res 2018 Jun;13(6):1061-1065

Department of Radiology, Huashan Hospital, Fudan University, Shanghai, China.

Research on brain function after brachial plexus injury focuses on local cortical functional reorganization, and few studies have focused on brain networks after brachial plexus injury. Changes in brain networks may help understanding of brain plasticity at the global level. We hypothesized that topology of the global cerebral resting-state functional network changes after unilateral brachial plexus injury. Read More
