Use of Magnetic Resonance Neurography for Sensory Nerve Injuries of the Head and Neck.

Background: Identification of peripheral nerve injuries of the head and neck can be challenging due to a broad spectrum of symptoms from neuropathic pain to headaches and migraine. This article aimed to present the clinical features and diagnostic workup of patients with acute and chronic peripheral nerve injuries of the head and neck using magnetic resonance neurography (MRN), to demonstrate potential advantages compared with conventional magnetic resonance imaging (MRI).

Methods: Patients who presented with suspected peripheral nerve injury were either referred for a conventional MRI or MRN.

AI generated synthetic STIR of the lumbar spine from T1 and T2 MRI sequences trained with open-source algorithms.

Background And Purpose: To train and evaluate an open-source generative adversarial networks (GANs) to create synthetic lumbar spine MRI STIR volumes from T1 and T2 sequences, providing a proof-of-concept that could allow for faster MRI examinations.

Materials And Methods: 1817 MRI examinations with sagittal T1, T2, and STIR sequences were accumulated and randomly divided into training, validation, and test sets. GANs were trained to create synthetic STIR volumes using the T1 and T2 volumes as inputs, optimized using the validation set, then applied to the test set.

Development of an interactive ultra-high resolution magnetic resonance neurography atlas of the brachial plexus and upper extremity peripheral nerves.

Purpose: To develop an educational, interactive, ultra-high resolution, in vivo magnetic resonance (MR) neurography atlas for direct visualization of the brachial plexus and upper extremity.

Methods: A total of 16 adult volunteers without known peripheral neuropathy underwent magnetic resonance (MR) neurography of the brachial plexus and upper extremity. To improve vascular suppression, subjects received an intravenous infusion of ferumoxytol.

Injury Patterns, Imaging Findings, and Prognosis for Muscle Strength Recovery in Surgical Infraclavicular Brachial Plexus Injuries.

Purpose: Historically, infraclavicular brachial plexus injuries (IBPIs) were considered neuropraxic injuries that would improve with nonsurgical intervention. However, more recent studies suggest that these injuries may benefit from surgical intervention. The aims of this retrospective study were to (1) describe injury patterns and associated injuries of isolated, traumatic IBPIs, (2) evaluate the concordance of preoperative ultrasound and magnetic resonance neurography with surgical findings of patients who underwent surgical intervention for IBPIs, and (3) describe outcomes of surgical intervention for these injuries.

Flexible Array Coil for Cervical and Extraspinal (FACE) for MR Neurography of the Occipital Nerves at 3 Tesla.

This technical report describes use of a novel, conformable receive-only radiofrequency coil for 3T magnetic resonance (MR) neurography in a cohort of patients with occipital neuralgia. Applying a sub-millimeter, isotropic three-dimensional double-echo steady-state sequence, detailed visualization of the occipital nerves and associated pathologies could be achieved.ABBREVIATIONS: ABC＝ definition; XYZ＝ definition.
